Re: [R] About concatenating strings

Hi lily, maybe this is what you want: strings1<-c(1.2,1.31,1.4,1.51) strings2<-c(2.1,2.22,2.3,2.44) paste(formatC(strings1,digits=2,format="f"), formatC(strings2,digits=2,format="f"),sep="-") Jim On Fri, Jan 6, 2017 at 4:56 PM, lily li wrote: > Sorry for the emails. I
