eventpct_cell: Factor level frequencies cell function

In etable: Easy Table

Description

Calculates frequencies or proportions of a certain level of factor x.

Usage

      eventpct_cell(x, y, z, w, cell_ids, row_ids, col_ids, vnames, vars, n_min,
      digits=1, digits2=0, event=2, type=1)

Arguments

x	The factor x for calculations
y	NOT USED
z	NOT USED
w	Weights for x factor, only if calculating weighted frequencies.
cell_ids	Index vector for selecting values in cell.
row_ids	NOT USED
col_ids	NOT USED
vnames	NOT USED
vars	NOT USED
n_min	Minimum n in the cell for useful calculation. Cells with n<n_min deliver no output.
digits	Integer indicating the number of decimal places (for percentages)
digits2	Integer indicating the number of decimal places (N, needed if N is not integer because of weighting)
event	The Number of factor level to calculate frequencies. from 1 to nlevels(x)
type	Type of representation, one of following. 1, pct (n) 2, n (pct) 3, pct 4, n 5, pct (n/N)

Examples

sex     <- factor(rbinom(1000, 1, 0.4), labels=c('Men', 'Women'))
event   <- factor(rbinom(1000, 1, 0.1), labels=c('no',  'yes'))
decades <- rbinom(1000, 3, 0.5)
decades <- factor(decades, labels=c('[35,45)','[45,55)','[55,65)','[65,75)'))
d<-data.frame(sex, decades, event)

tabular.ade(x_vars=c('event'), xname=c('Event'),
   rows=c('sex','ALL'), rnames=c('Gender'),
   cols=c('decades', 'ALL'),   cnames=c('Age decades'),
   data=d, FUN=eventpct_cell)
