ggplot2: Quick Heatmap Plotting, reshape?
ggplot2, heatmap, r
Solution
ggplot2 doesn't seem to be loading the `scales` library automatically anymore, so to use the `rescale` function, you have to explicitly load `library(scales)`.
When you get an error about a function not being found, the `??` command can help you find which package the function might be in, e.g. `??rescale`.
Problem
I'm trying to reproduce the heatmap presented on this blog by following their tutorial, but when I try to run their Jan 2010-code I get an error when asking for, ``` nba.m <- ddply(nba.m, .(variable), transform, rescale = rescale(value)) Error in eval(expr, envir, enclos) : could not find function "rescale" ``` Reproducible code is available on the blog mentioned above I'm using ggplot2_0.9.0 and R 2.14.2. Also, I did read this thread here on stackoverflow.com. Any ideas to what might be wrong?
