Question

This may be a super dumb question, that I feel like I should know the answer to.

I am using a package called maxstat, when I run a test I get output such as the following:

Maximally selected Wilcoxon statistics using none

data:  x and scores 
M = 8.3107, p-value = NA
sample estimates:
estimated cutpoint 
            0.6421 

I call this output “x” and I only want to retrieve the value of the estimated cutpoint. So I try:

> x$estimate
estimated cutpoint 
        0.6421 

How do I just get the value 0.6421 without the attached name “estimated cutpoint”?

I want to put this value in a table and when I use cbind or rbind to attach the value(s) the name gets attached as well.

Answer 1

See ?unname, e.g.

unname(x$estimate)

Although all this does is drop the "names" attribute. If you have several of these to un-name, it might be easier to bind them all together and then get rid of the row or column names en masse via one of:

rownames(obj) <- NULL
colnames(obj) <- NULL

Or

dimnames(obj) <- list(NULL, NULL)

where obj is the object containing the data you wish to un-name.
