[R] RStudio 1.1.453 - Windows 10 - How to subset named vector by names that are NOT "foo"
H i All, If I have this vector:> vect <- c(foo = 11, bar = 2, norf = 45)I can have a subset that has only "bar and "norf" this way:> vect[c("bar","norf")]Now how do I achieve the same by asking it for a subset that simply excludes "foo"? I tried all these, resulting in errors: vect[-"foo"] vect[-c("foo")] vect[!"foo"] vect[!c("foo")] Thanks! [[alternative HTML version deleted]]

Hi, You need to tell R to look in the names component of your vector. Here are three different ways: vect <- c(foo = 11, bar = 2, norf = 45) vect[!(names(vect) %in% c("foo"))] # easily generalizable to a longer list vect[!grepl("foo", names(vect))] vect[!(names(vect) == "foo")] There are many more ways to do this, all predicated on matching a string within the character vector containing the names of your object. Also, on this list we don't care at all if you're using R Studio, or what the version is. We do potentially care what version of R itself you are using.

Awesome, Sarah, thanks! And thanks for the clarification about declaring the version of R.

You can do Vect[-grep (?foo?, names(vect))] On Tue, 31 Jul 2018 at 11:12 PM, ??????? ????
