freq {prettyR} | R Documentation |
Calculates one or more frequency table(s) from a vector, matrix or data frame.
freq(x,variable.labels=NULL,display.na=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. |
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.
