[R] print and lapply....

[akshay kulkarni]

Dear Andrew
                         It doesn't work:

> lapply(TP,function(x){print(x^2)})
[1] 1
[1] 4
[1] 9
[1] 16
[[1]]
[1] 1

[[2]]
[1] 4

[[3]]
[1] 9

[[4]]
[1] 16

Basically, lapply() is implemented by a for loop. So there must be some way right?

tHanking you,
Yours sincerely,
AKSHAY M KULKARNI

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
