[R] String manipulation and formatting

[Hans-Joerg Bibiko]

Hi,

an other way without any libraries and written as a one-line-command  
would be something like this:


xify <- function(x)
{
	gsub("[0-9]","X",
	sprintf(
		paste(
			"%",
			ifelse(
				format(x,digit=1)==as.character(x),
				paste(as.character(x),".0",sep=""),
				as.character(x)
			),
			"f",sep=""
		)
		,10^(trunc(x)-10*x+10*trunc(x)-1)
	)
	)
}


The only disadvantage is that something like xify(4.8) produces [1]  
"X.XXXXXXXX".
