Hello,
I'm having trouble using the td.tapply function right now. All I get is a null result. I can get (with different syntax) this concept to work with the regular tapply function on a regular dataframe, but not with the "td" function on a "td" dataframe. Here's my R syntax:
my_array <- td.tapply(sops["A"], sops["B"],
+ FUN=function(y){grepl(pattern="pattern", y, ignore.case=TRUE)})
sops is a teradata data frame. A and B are columns within that dataframe. B is data that *could* be a factor, but in the teradata data frame, all the variables appear to be of a type chr(0). Thanks for your help.
Brian
