Hello, Is there a better way to use paste such as: a = paste(colnames(list.indep)[1],colnames(list.indep)[2],colnames(list.indep)[3],colnames(list.indep)[4],colnames(list.indep)[5],sep="+")> a[1] "aa+dummy1+dummy2+bb+cc" I tried a = paste(colnames(list.indep)[1:5],sep="+")> a[1] "aa" "dummy1" "dummy2" "bb" "cc" But it will not give me the way I want.

It looks like you want collapse rather than sep:> list.indep <- data.frame(aa=1:4, dummy1=1:4, dummy2=1:4, bb=1:4, cc=1:4) > paste(colnames(list.indep), collapse="+")[1] "aa+dummy1+dummy2+bb+cc" On Thu, Mar 21, 2013 at 11:15 AM, Yuan, Rebecca <rebecca.yuan at bankofamerica.com> wrote:> Hello, > > Is there a better way to use paste such as: > > a = paste(colnames(list.indep)[1],colnames(list.indep)[2],colnames(list.indep)[3],colnames(list.indep)[4],colnames(list.indep)[5],sep="+") > > > >> a > > [1] "aa+dummy1+dummy2+bb+cc" > > > > I tried > > > > a = paste(colnames(list.indep)[1:5],sep="+") > > > >> a > > [1] "aa" "dummy1" "dummy2" "bb" "cc" > > But it will not give me the way I want. > > Thanks, > > Rebecca > >-- Sarah Goslee http://www.functionaldiversity.org
?dat2<-as.data.frame(matrix(1:20,ncol=5))
?colnames(dat2)<-
c("aa","dummy1","dummy2","bb","cc")
?paste(colnames(dat2),collapse="+")
#[1] "aa+dummy1+dummy2+bb+cc"

Hello,
Is there a better way to use paste such as:
a =
paste(colnames(list.indep)[1],colnames(list.indep)[2],colnames(list.indep)[3],colnames(list.indep)[4],colnames(list.indep)[5],sep="+")
> a
[1] "aa+dummy1+dummy2+bb+cc"
I tried
a = paste(colnames(list.indep)[1:5],sep="+")
> a
[1] "aa" "dummy1"? ? ? ? ? ? "dummy2"? ? ? ? ? ?
? "bb"? ? ? ? ? ? ? ? ? "cc"
But it will not give me the way I want.
Thanks,
Rebecca

Hello A.K.,
