Answer 1

Try this approach using functions from base:

# dummy data:
df<-data.frame(v1=c("78%", "65%", "32%"), v2=c("43%", "56%", "23%"))

# function
df2<-data.frame(lapply(df, function(x) as.numeric(sub("%", "", x))) )

As per the comments provided this first strips away the percentage signs, and then converts the columns from factors to numeric. I've changed the original answer from apply to lapply following @thelatemail's suggestions.
