dat <- c(1,2,3)

names(dat) <- c(-2329,   -1399, -669.4)
dat

  -2329  -1399 -669.4

Hi,

I have the following data that looks like this:

names(dat)

[1] "(-2329,-2319]"         "(-1399,-1389]"         "(-669.4,-659.4]"

How can I modify those names into just this?

[1] -2329   -1399 -669.4

I would imagine that what is wanted is slightly (!) more general.   
Something
along the lines of:

sapply(strsplit(names(dat),","),function(x){gsub("\\(","",x[1])})

Someone who knows more about regular expressions could doubtless do this
much more slickly, just using gsub() and without recourse to strsplit(),
but the foregoing works.
