With the R prompt still active, data may be cleanly viewed (not
edited) in a separate window by a simplification of function xless in
Hmisc by Frank Harrell:
look. <- function (x, ...,
title = substring(deparse(substitute(x)), 1, 20))
{
page(x, method = "print", title = title,options=(width=150))
invisible()
}
Names alone can be viewed separately as well:
names.
function (x, ...,
title = c(substring(deparse(substitute(x)), 1, 20)))
{ title=paste(title," ...NAMES")
page(names(x), method = "print", title = title,options=(width=150))
invisible()
}
Both functions work in Windows XP and Mac OS X Leopard under R 2.7.1
and earlier.
