Usage

get_col(matrix, rows, col)

get_row(matrix, row, cols)

Arguments

matrix	matrix.
rows	numeric; rows to subset; like with `[`, this argument can be left empty to designate all rows.

Examples

m <- matrix(NA,dimnames=list('r1','c1'))
m[1,1] # = NA; R removes both names
get_col(m,rows=1,col=1) # = c(r1=NA) keeps colname
get_row(m,row=1,cols=1) # = c(c1=NA) keeps rowname
