Calculates one or more frequency table(s) from a vector, matrix or data frame.
Usage
freq(x,variable.labels=NULL,display.na=TRUE)
Arguments
x
a vector, matrix or data frame.
variable.labels
optional labels for the variables. The default is
the names 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.
Value
A list with one or more components. Each component includes the
values of the relevant variable as the names.
Details
freq calls tabulate to get the frequency counts and builds
a list with one or more components containing the value labels and counts.
Note that a limit on the number of bins has been removed, so passing a
numeric vector with many levels may produce a huge, useless "frequency"
table.
