Hi everyone, I was wondering if there was a simple way to assign a color to a cell based on value in a data frame and return the cell as an image? For example, if the value is >1, then blue, if between 1 and 2, green, if between 2 and 3, yellow, etc. I tried using a heatmap function but I was hoping there was an easier way to do this. Thanks, Sumukh
Assigning colors to cells

Use the cut() function to produce the interval categories and color
names in the data frame and then pass that variable to the col =
argument in the appropriate plot function. Something like
mydata$mycolors <- cut(mydata$value, c(-Inf, 1, 2, 3, Inf), label =
c('blue', 'green', 'yellow'))
Ask an abstract question, get an abstract answer...
