this seems l ike it shouldn't be that hard but i give up.
if i have a string say, temp<-"01", I want to increase it by 1 so that
it becomes "02". but the following code obviously won't work when the
input string is say "10" because then it gives "011" when I just want
"11". uuugh.
does someone know an easy way ( i guess hard is fine too. beggars can't
be choosy ) around that ? the code below probably explains more
clearly what i mean. thanks.
temp1 <- "01"
paste("0",as.numeric(temp1)+1,sep="")
temp10 <- "10"
paste("0",as.numeric(temp10)+1,sep="")
string to numeric question

See ?sprintf, e.g. x2Str <- sprintf("%02d", as.integer(x)) where 'x2'
is numeric. Use x <- as.numeric(xStr) to convert string 'xStr' to
numeric and x <- x + 1 to change the value.
