Dear all,
After I work around, I found in my list of data with only one row which
need to remove or make it as matrix.
Here I write again my other toy example:
x - list(matrix(1:20, 5, 4),matrix(1:20, 5, 4),matrix(1:20, 5,
4),matrix(1:20, 5, 4),matrix(1:20, 5, 4))
y - list(c(1, -1, -1, 1,

Dear all,

Dear all,
I am still working with list.
If I have an empty list how can I remove from list data.
Here is a toy example:
x - list(matrix(1:20, 5, 4),matrix(1:20, 5, 4),matrix(1:20, 5,
4),matrix(1:20, 5, 4),matrix(1:20, 5, 4))
y - list(c(1, -1, -1, 1, 1),c(1, 1, -1, -1, -1),c(1, 1, 1, 1, 1),c(1,

Here is a function I use a lot to do this:
delete.NULLs - function(x.list){ # delele null/empty entries in a list
x.list[unlist(lapply(x.list, length) != 0)]
}
delete.NULLs(nc.test)
[[1]]
[,1] [,2] [,3] [,4] [,5]
[1,]16 11 161
[2,]49 14 191
[3,]
