[R] use variable value to create new variable name

[Peter Alspach]

Tena koe Maciek

It is possible; e.g.:

i <- 3
assign(paste('myVar', i, sep=''), 1:5)
myVar3
[1] 1 2 3 4 5

Personally, I find it is more convenient to use a list so that instead of myVar1, myVar2 etc I have a list object, myVar, with each element equivalent to myVar1, myVar2 etc.

HTH ...
