Calculate a frequency table
Calculates one or more frequency table(s) from a vector, matrix or data frame.
freq(x,variable.labels=NULL,display.na=TRUE,decr.order=TRUE)
x |
a vector, matrix or data frame. |
variable.labels |
optional labels for the variables. The default is the name of the variable passed or the names attribute if the variable has more than 1 dimension. |
display.na |
logical - whether to display counts of NAs. |
decr.order |
Whether to order each frequency table in decreasing order. |
freq calls table to get the frequency counts and builds a list with one or more components containing the value labels and counts.
A list with one or more components. Each component includes the values of the relevant variable as the names.
The limit on the number of bins has been removed, so passing a numeric vector with many levels may produce a huge, useless "frequency" table.
