Writing a function to return column position XXXX
Hello everyone,
I am writing my own function to return the column index of all variables
(these are currently character vectors) in a data frame that contain a
dollar sign($). A small piece of the data look like this:
can_sta can_zip ind_ite_con ind_uni_con AL 36106 $251,895.80 $22,874.43
AL 35802 $141,373.60 $7,100.00 AL 35201 $273,208.50 $18,193.66 AR
72404 $186,918.00
$25,391.00 AR 72217 $451,127.00 $27,255.23 AR 7.28E+08 $58,336.22 $5,293.82
So far I have:
col.id<-function(x) any(grep("$",x))
sapply(cand2,col.id)...
