Re: [R] heat color on age visible on ordination

Hi Jackson, I'll take a wild guess at "What is wrong?". You only got one end of the color vector, probably the purple end. As my recollection of principal components analysis is of a data reduction method, you probably have a lot fewer than 500 points on your plot. If you only have, say, 50 values

Re: [R] heat color on age visible on ordination

Hi Jackson, One way to assign colors to values is: library(plotrix) ages<-seq(1, 5, by = 100) agecol<-color.scale(ages,extremes=c("purple","red")) Then just use "agecol" for your point colors. Jim On Tue, May 24, 2016 at 11:57 AM, Jackson Rodrigues wrote: >

Hi everybody, I have a big matrix spread over a long time period. I would like to make a ordination plot (PCA, CA, DCA etc) of this matrix and look for patterns on time by exploring a color scheme (I have heat color in mind). The idea is to use a progressive color scheme ranging from red (the

Re: [R] promoting scalar arguments to vectors in a function

Scalar values in R are just vectors of length 1. The "promotion" you are thinking of is "recycling" that automatically occurs when vectors of different lengths are supplied to certain operations. One shortcut might be to put them all into a data frame using the data.frame() function.
