Hello here. I'm struggling to understand R's subsetting behavior in couple
of edge cases - subsetting row in a single column matrix and subsetting
column in a single row matrix. I've read R's docs several times and haven't
found answer.
Consider following example:
a = matrix(1:2, nrow = 2, dimnames = list(c("row1", "row2"), c("col1")))
a[1, ]
# 1
It returns *unnamed* vector `1` where I would expect named vector. In fact
it returns named vector when number of columns is > 1.
Same issue applicable to single row matrix. Is it a bug? looks very
counterintuitive.
