Sedgwick Reserve, where I studied pollen and seed dispersal in Quercus agrifolia and Q. lobata.

 

Intron length distributions within the 5'UTR, coding sequence, and 3'UTR of Arabidopsis thaliana genes.

plotGFF() is an R function to produce a simple graphical plot of the annotatation contained within a GFF file. See plotGFF-example.png below for an example.  5k v. 7 Sep 8, 2011 4:00 AM Douglas Scofield
plotSpatialPies-0.2.zip
View Download
plotSpatialPies() is an R function to plot pie charts representing fractions of a code at particular lat/long locations. Useful for examining e.g., genotype proportions in space. Requires the R package "plotrix", for its very useful floating.pie() function.   5k v. 1 Oct 4, 2011 6:28 AM Douglas Scofield
