fmla |
a formula whose right-hand side names the variables to be used for tabulation. The optional left-hand side specifies a variable to be used for weights. |
useNA |
whether to include NA levels. The default is "ifany". Can also be set to "no" or "always". |
pct |
margins to be scaled to sum to 100. This is the vector of margin indices on which percentages are conditioned. For example, with the call |
pr |
margins to be scaled to sum to 1. This is the vector of margin indices on which percentages are conditioned. |
total.margins |
if FALSE, generate table without margins |
weights |
(not working temporarily) instead of generating a frequency table, generate a table with the sum of the weights |
keep |
names of margins to keep with 'Tab', default = "All". To drop all margins, use default = "". |
An object of class 'table' of dimension equal to the number of variables, with optional margins showing totals. Elements of the matrix can be frequencies, relative frequencies, percentages or sums of weights.
