Dear R-community,
I have got a list of vectors and would like to extract the first two
elements of each vector to a new list.
My list is of the style:
my.list = list(c("a", "b", "c"), c("d", "e"), c("f", "g", "h", "i"), ...)
#I want:
new.list = list(c("a", "b"), c("d", "e"), c("f", "g"), ...)
# As
my.list[[3]][1:2]
# is [1] "f" "g"
# I thought
my.list[[1:3]][1:2]
# would be
# [[1]]
# [1] "a" "b"
# [[2]]
# [1] "d" "d"
# [[3]]
# [1] "f" "g"
# but is: 'Error: recursive indexing failed at level 2'
I think it should be easy, but none of my tried combinations of '['
and 'c(' worked.
Who can help?
Patrick
