Expression Deparsing

Syntax

deparse(expr)

Value

This function turns unevaluated expressions into character strings (a kind of inverse parse). A typical use of this is to create informative labels for data sets and plots. The following example shows a simple use of this facility. It uses the functions deparse and substitute to create labels for a plot which are character string versions of the actual arguments to the function myplot.

See Also

substitute, parse.

Examples

myplot <- function(x, y) plot(x, y, xlab=deparse(substitute(x)), ylab=deparse(substitute(y)))
