Hi Karim, I'm not sure that this is what is causing the error, but your "list" is actually a vector. The following runs, but the function is obviously not working:
sapply(list, function(x) as.character(attriColorValue(x,list,colors=c("blue","white","red"),feet=1))) There is probably a better name for your vector than "list".
