Hi R users, I have following data frame
df<-data.frame(q1=c(0,0,33.33,"check"),q2=c(0,33.33,"check",9.156), q3=c("check","check",25,100),q4=c(7.123,35,100,"check")) and i would like to replace every element that is less then 10 with . (dot) in order to obtain this: q1 q2 q3 q4 1 . . check . 2 . 33.33 check 35 3 33.33 check 25 100 4 check . 100 check I had a lot of difficulties because each variable is factor. Could someone help me with this? Thanks in advance for any help.
