Further information
1. If
cmd contains more than one statement, the returned value is the result of the last one.
2. The Mosel array
arr must have the same number of dimensions as the R array; NA entries in R are skipped and corresponding entries in
arr are left unchanged (note that
arr is not cleared before loading R data).
3. Supported index types for the
arr array are string and integer. In the case of strings, the R array must have a valid
names or
dimnames attribute for the corresponding dimension; in the case of integers, the R integer indices (1 to n) are used. All entries of the R array are converted to the same type as the destination array within R.
