I'm trying to re-code a file from R into MATLAB. I have two questions:
(1) The R file has
n <- ybari <- ss <- vars <- sz <- skews <- rep(0, ngroups)
I'm aware of the general meaning of the initialization, but what is the equivalent MATLAB input of the above for an .m file?
(2) (also from the R file) I'm trying to generate from an N x 2 matrix a vector whose number of entries is the number of groups of the data, and whose entries give the number of members in the group. For example,
The above has 2 groups (groups represented by the second column), group 1 and group 2. Each group has 3 members, so the vector would look like
The R code for the above is
for (i in 1:N) # n = vector giving number in each group
n[group[i]] = n[group[i]] + 1
What is the equivalent MATLAB command?
