[R] Re turning variable names with variables (in a function)

[Shubha Vishwanath Karanth]

You can just go for a small change in the function as,

results <- cbind(se, upper, lower, cv)
OR
results <- data.frame(se, upper, lower, cv)

Subject: [R] Re turning variable names with variables (in a function)


Dear R Users,

I have written a function that returns 4 variables. I would like to have
the
variables returned with their variable names, is this possible?

----------------------------- R Code -------------------------
mc.error <- function(T, p=0.05){
	se <- sqrt((p)*(1-(p))/T) # standard error
	upper <- p+(1.96*se) # upper CI
	lower <- p-(1.96*se) # lower CI
	cv <- se/p # coefficient of variation
	results <- c(se, upper, lower, cv)
	return(results) 
}
----------------------------- R Code -------------------------

This returns (or something like this, depending on the value of T):

[1] 0.004998685 0.059797422 0.040202578 0.099973695

I would like:

[1] se=0.004998685 upper=0.059797422 lower=0.040202578 cv=0.099973695

Or even better:

se                 upper             lower            cv
0.004998685   0.059797422   0.040202578   0.099973695

Any help is much appreciated, thanks.

Steve
