Hi, Try this,
snip = function(x, n=1) { rand = sample(1:3, 1) print(paste("using algorithm #", rand)) switch(rand, '1' = head(x, length(x) - n), '2' = x[ seq(1, length(x) - n) ], '3' = x[ - seq(length(x), by=-1, length=n) ]) } snip(1:5) HTH, but please do read the posting guide. baptiste On 18 April 2011 12:51, empyrean <ctr...@ucdavis.edu> wrote: > Hey guys, > > I've search a few threads about deleting a value from a vector, but no one > has addressed this question so far. > > I want to delete the last value from a string of values > > I have: > > r = [ 1, 2, 3, 4, 5 ], and i want to make r2 = to [ 1, 2, 3, 4] > > So that r2 is just like r, except that it missing the final value. > > Thanks, > > -- > View this message in context: > http://r.789695.n4.nabble.com/Deleting-the-last-value-of-a-vector-tp3456363p3456363.html > Sent from the R help mailing list archive at Nabble.com. > > ______________________________________________ > R-help@r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code. > ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
