Thanks a lot! This is very helpful.
If I have to extend this to one more condition say assign "blue" if both the
corresponding labels have "_Tongue_dorsum", is there a straight forward function. Doing
something like below is overriding the colors assigned by the first statement.
col<- ifelse(grepl("_Anterior_nares", xlabels)& grepl("_Anterior_nares", ylabels),
"red", "black")
col<- ifelse(grepl("_Tongue_dorsum", xlabels)& grepl("_Tongue_dorsum", ylabels), "blue",
"black")
Hi Karthik,
Your problem is that you are assigning all of the values to "col" twice.
If you reverse the order of the statements you will get the red/black
color set. Try this:
col<-rep("black",dim(cdh1)[1])
col[grepl("_Anterior_nares", xlabels) &
grepl("_Anterior_nares", ylabels)]<-"red"
col[grepl("_Tongue_dorsum", xlabels) &
grepl("_Tongue_dorsum", ylabels)]<-"blue"
If your two conditions specify disjunct sets, that is, no case satisfies
both conditions, you should have the correct vector of colors.
