[R] Object of type 'closure' not subsettable

[Muhammad Rahiz]

Thanks Barry for the clarification.

With regards to the following;

d2[[i]] <- file[[i]] - mean

renamed to

d2[[i]] <- f[[i]] - m

The object f contains the following so clearly f is subsettable

[[1]]
  V1
1 10
2 10
3 10

[[2]]
  V1
1 11
2 11
3 11

[[3]]
  V1
1 12
2 12
3 12

My plan is to subtract m from each subset of f and to store the output 
as each individual subsets. So,

output1 <- f[[1]] - m
output2 <- f[[2]] - m
output3 <- f[[3]] - m

If I run the following to achieve the desired result, there is an error 
as written in the subject heading.

d2[[i]] <- f[[i]] - m

If I run the following, the error is gone but I'm not getting the output for each individual file I require

d2 <- f[[i]] - m

The issue is, how do I make d2 subsettable?


Thanks.

Muhammad
