Dear members,
I have the following code and output:
TP <- 1:4
lapply(TP,function(x){print(x);x^2})
[1] 1
[1] 2
[1] 3
[1] 4
[[1]]
[1] 1
[[2]]
[1] 4
[[3]]
[1] 9
[[4]]
[1] 16
How do I make the print function output x along with x^2, i.e not at the
beginning but before each of x^2?
Many thanks in advance....
THanking you,
Yours sincerely

Hello,
Here are two options, with ?cat and with ?message.
TP <- 1:4
lapply(TP, function(x){
cat("x =", x, "x^2 =", x^2, "\n")
})
lapply(TP, function(x){
msg <- paste("x =", x, "x^2 =", x^2)
message(msg)
})
Hope this helps,
Rui Barradas
