How does this differ from cell_limits? Two ways. First, the input can
have length greater than 2, i.e. the columns can be specified as 1:n.
If the length is greater than 2, both the min and max are taken with
NA.rm = TRUE. Note it is not possible to request non-contiguous
columns, i.e. columns 1, 2, and 5. In this case, the requested columns will
run from the minimum of 1 to the maximum of 5. Second, the input can be given
in the letter-based format spreadsheets use to label columns.
Usage
cell_cols(x)
Arguments
x
vector of column limits; if character, converted to numeric; if
length greater than two, min and max will be taken with NA.rm = TRUE
