Hello,
When I use "apply" on a data frame, it seems like I get an error when I have a
column that is not numeric. Via trial and error I realized that if I remove
that column, I can get it to run. Is there a better way to tell the function
not to worry about the character columns, especially since I am not even trying
to do any calculations on it?
R_Cat is the character column that is causing error and I am trying to do
calculations on t5R.
Data_F_Cat$t5R_Cat = apply(Data_F[,names(Data_F) != "R_Cat"],1,function(row) {
ifelse( abs(row["t5R"]) <Thresh1, 0,
ifelse( abs(row["t5R"]) <Thresh2, ifelse( row["t5R"] <0, -1, 1),
ifelse( abs(row["t5R"]) <Thresh3, ifelse( row["t5R"] <0, -2, 2),
ifelse( abs(row["t5R"]) <Thresh4, ifelse( row["t5R"] <0, -3, 3),
ifelse( abs(row["t5R"]) <0, -4, 4)))))
})
Thank you,
Pooya.
