[R] GSUB function and regex problem

[Rui Barradas]

Hello,

Try reading your data with option stringsAsFactors = FALSE. It seems 
that your strings are being read as factors, which are coded as integers.

DataGoogle1 <- read.csv(file = "DataGoogle2.csv", header = T, 
stringsAsFactors = FALSE)


Hope this helps,

Rui Barradas
