[R] dimensions of a all objects

[ONKELINX, Thierry]

You need something like this: 
sapply(objects() , function(x)(dim(eval(parse(text = x)))))

a <- rnorm(1)
b <- matrix(rnorm(4), ncol = 2, nrow = 2)
sapply(objects() , function(x)(dim(eval(parse(text = x)))))

$a
NULL

$b
[1] 2 2

Cheers,

Thierry

Why will the following command not work
sapply(objects(),dim)
What does it say about the objects list? What does it say about the dim
command?

Likewise, the following also does not work
all<-ls()
for (f in all) print(dim(f))
