Re: [R] About concatenating strings

[Jim Lemon]

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="-")

Re: [R] About concatenating strings

[lily li]

Sorry for the emails. I just checked and the problem is still there. Is
there a proper way to reformat the decimal places, such as three or four
decimal places? Thanks.

If maintain four decimal places, the numbers are: 1.2000, 1.3100, 1.4000,
etc.

Re: [R] About concatenating strings

I found that the last column is the digits 2.00, so the problem is solved.

[R] About concatenating strings

[lily li]

Hi R users,

I'm trying to concatenate two strings, while each string has numbers.
For example, strings1 = c(1.2, 1.31, 1.4, 1.51, etc), strings2= c(2.1,
2.22, 2.3, 2.44, etc). I want to have all decimals for the two strings,
such as: strings1= c(1.20, 1.31, 1.40, 1.51, etc), string2 = c(2.10, 2.22,
2.30, 2.44, etc).
After concatenating, they become c(1.20--2.10, 1.31--2.22, 1.40--2.30,
1.51--2.44, etc)
I use the code below, but after digits=2 in the parentheses, the length of
each string has one more. What is the problem and how to do it another way?
Thanks.

cons  = paste(c(strings1, digits=2), c(strings2, digits=2), sep='-')
