You can now also use the fig.cap argument in the chunk header to write the title you want to have for your table. For referencing, you have to refer to the chunk label (in this case "mytable"). The title argument in stargazer creates the element, this is why the html title is inserted there.

I don't know how to achieve this with stargazer. I will note that bookdown cross-references are a pretty recent feature, and that stargazer has not been updated in over 3 years, so issues are bound to arise.

The northern stargazer is not listed as endangered or vulnerable with the World Conservation Union (IUCN). The IUCN is a global union of states, governmental agencies, and non-governmental organizations in a partnership that assesses the conservation status of species.

Distinctive Features

The northern stargazer is well adapted to life under the sand. The body is moderately elongate. Its pectoral fins act as shovels, enabling the fish to bury itself in a matter of seconds. The eyes and nostrils are strategically located on the top of the head so that they will remain above the sand when the fish is buried. Unlike most species of fish that bring water in through their mouths to breathe, the stargazer breathes through its nostrils. The nostrils are protected from sand grains by fleshy, comb-shaped fringes. The mouth also has these fringes around it to keep sand out while the fish is buried. The eyes are capable of protruding for a short distance, appearing stalked, for a limited amount of time to allow the fish to gaze over the bottom. The stargazer does this by filling the tissues behind the eyes with liquid. The gill slit is narrow and drawn backwards and upwards into a short, baggy tube. This tube carries waste water away from the fish and outside the surrounding sand. This fish possesses a special talent: it is able to create weak electrical currents from a specialized organ located behind the eyes.

Coloration

The blackish-brown body is covered with white spots that gradually increase in size towards the rear of the body. Top of head and body has small, closely spaced white dots. There are three dark, horizontal stripes on the tail. The southern stargazer, Astroscopus y-graecum, closely resembles the northern stargazer in appearance and in life history. An easy way to tell these two species apart is to note the middle stripe on the tail. On the northern stargazer, this stripe extends onto the rear portion of the body; on the southern stargazer this stripe does not extend pass the tail.

Food Habits

The diet of the northern stargazer consists of smaller fish that are unlucky enough to swim near it. The electrical organ is not used to capture prey. Its main function is to protect the stargazer from anything that may pose a threat to the well being of the fish. The stargazer instead relies on its camouflage and lies in wait for a small fish to swim near it. Once the prey is in range, the stargazer rises from the sand and in an instant swallows the fish whole.

Reproduction

True to its benthic nature, the northern stargazer spawns on the bottom during the late spring and early summer months. The eggs are small, transparent, and slowly float to the surface. These eggs hatch into small, transparent larvae that live in the water column. These pelagic larvae grow rapidly, feeding off the yolk sac until they reach about 6-7 mm in length. When they reach this length, the yolk sack has been completely consumed and the larvae begin feeding on other larvae in the water column, including some of their own kind. They also begin to acquire a black color that deepens with time. As they grow, a bright yellow spot appears on the chin. The electric organs begin to form when the larvae reach about 12-15 mm in length. At this length the larvae will migrate to the bottom and become a true juvenile. Juvenile stargazers tend to move inshore to sandy bays, where they may stay for several years. The juveniles will develop the characteristic patterns of the adults during the time spent in the sandy bays. The eyes, which were on the side of the larval head, will also migrate to the top of the head. When the juveniles reach about a foot in length, they move offshore and become adults.

stargazer is a new R package that creates LaTeX code for well-formatted regression tables, with multiple models side-by-side, as well as for summary statistics tables. Its latest version, released in early January 2013, can also output the content of data frames directly into LaTeX. Compared to available alternatives, stargazer excels in three regards: its ease of use, the large number of models it supports, and its beautiful aesthetics.

stargazer supports objects from the most widely used statistical functions and packages. These include lm, glm, svyglm, plm, betareg, gee, gam, polr, survreg , coxph, tobit (AER), ivreg (AER), zeroinfl (pscl), hurdle (pscl), multinom (nnet), as well as their implementations in Zelig. In addition, stargazer also supports several Zelig models for social network analysis: cloglog.net, gamma.net, probit.net, and logit.net. The number of models and objects can stargazer can accommodate puts it ahead of most of the alternative R-to-LaTeX options. As the development of the package continues, this list will continue expanding to include linear mixed effects models, matching models, as well as new, user-made, or customized statistical models.

stargazer is very pleasing to the eye, and allows the user to customize the formatting of the resulting table, including all variable labels. Below is an example of a good-looking, complex regression table created by stargazer:

stargazer, of course, is not the only R package that creates LaTeX code from R statistical output. Other packages with similar capabilities include apsrtable, xtable, memisc, texreg and outreg. Each of these has its own strengths and weaknesses, and users should explore all of them to find the best fit for their needs.

As a doctoral student in Political Economy and Government at Harvard University, I saw an urgent need for an easy-to-use tool to create well-formatted stargazer tables. Although other packages were available for this task, none of them combined a large number of supported models, good aesthetics, and simplicity of use in a way that I thought would be ideal.

In this guide, we will focus on stargazer. This package offers a very nice, smart, and easy-to-use alternative to non-LaTeX users, in particular, the ability to import editable tables into a Word document. This presentation will show some of the options stargazer offers, the contents are based on the documentation from the package available in the following links:

stargazer will automatically recognize the type of object, and will produce the appropriate output. In the case of data frames, it will display summary statistics. Therefore, if we want to create a summary statistics table including all variables in a data frame, we can directly put the data frame name in.

The 'out="table1.txt" is to specify the name of the file we created using stargazer. The table will be saved in your current working directory with whatever name you write in the out option. You can open this file with any word processor. If you are not sure about your current working directory, just type in getwd() in the Console.

Note that when you apply any function to the coefficients or other statistics, stargazer automatically reevaluates t values using the updated coefficients. Therefore, the significance level will depend on the new value.

Stargazer mice have spike-wave seizures characteristic of absence epilepsy, with accompanying defects in the cerebellum and inner ear. We describe here a novel gene, Cacng2, whose expression is disrupted in two stargazer alleles. It encodes a 36-kD protein (stargazin) with structural similarity to the gamma subunit of skeletal muscle voltage-gated calcium (Ca2+) channels. Stargazin is brain-specific and, like other neuronal Ca2+-channel subunits, is enriched in synaptic plasma membranes. In vitro, stargazin increases steady-state inactivation of alpha1 class A Ca2+ channels. The anticipated effect in stargazer mutants, inappropriate Ca2+ entry, may contribute to their more pronounced seizure phenotype compared with other mouse absence models with Ca2+-channel defects. The discovery that the stargazer gene encodes a gamma subunit completes the identification of the major subunit types for neuronal Ca2+ channels, namely alpha1, alpha2delta, beta and gamma, providing a new opportunity to understand how these channels function in the mammalian brain and how they may be targeted in the treatment of neuroexcitability disorders. 17dc91bb1f
