In arnima-github/arni: Arni's Toolbox

Transform Table to Cohort Format

Description

Transform Year | Age | Value table into cohort format, and possibly create a plot.

Usage

cohorts(x, xtab = TRUE, plot = TRUE, log = "", base = exp(1),
  type = "l", lty = 1, xlab = "Age", ylab = "Value", ...)

Arguments

x	a Year | Age | Value table (three column data frame or crosstabbed data frame, matrix, or table).
xtab	whether the output should be returned as a wide crosstab table (otherwise long data frame).
plot	whether a cohort plot should be created.
log	a string specifying which axes should be log-transformed: "", "x", "y", "xy", or TRUE -> "y".
base	the log base used if log is TRUE.
type	passed to matplot.
lty	passed to matplot.
xlab	passed to matplot.
ylab	passed to matplot.
...	passed to matplot.

Value

Crosstab table in cohort format, of class c("xtabs","table").

Warning

Zero values are treated as NA.

Note

If x is a three column data frame, column 1 must contain the year, column 2 the age, and column 3 the value. If x is crosstabbed, rows must be years and columns must be age.
