[R] filling data into objects

[Henrique Dallazuanna]

Perhaps:

for(i in 1:100)assign(sprintf("Informative.data.class%s", i),
rnorm(100, 0.25,1))
for(i in 1:100)assign(sprintf("Uninformative.data.class%s", i), rnorm(900))

Or working with a list:

Informative <- replicate(100, rnorm(100, 0.25,1))
Uninformative <- replicate(100, rnorm(900))
