I am new to R. Used to use FORTRAN. R is so different from FORTRAN. The
following codes would work in FOTRAN. I am trying to put an upper limit at
120. If the score is > 120, it is assigned 120. Or else, keep the original
values.
version 1:
equated<-11
result<-11
equated<-c(111.0,112.06, 112.9, 113.8, 115.0, 116.2, 117.0, 118.0, 120.5,
120.5, 120.5)
for (i in 1:11){
if (equated > 120) result[i]<-120
if (equated < 120) result[i]<-equated[i]
result<-result
result
}
result
version2:
if (equated > 120) result<-120
if (equated < 120) result<-equated
If any of you can help, I would appreciate that.

What about these two options? #One way ifelse(equated > 120, 120, equated) #Another way equated[equated > 120] <- 120 HTH, Josh On Mon, Jul 26, 2010 at 10:26 AM, ying_chen wang <gracedrop.wang at gmail.com> wrote:> I am new to R.

Is this what you want:> equated<-c(111.0,112.06, 112.9, 113.8, 115.0, 116.2, 117.0, 118.0, 120.5,+ 120.5, 120.5)> equated[equated > 120] <- 120 > equated[1] 111.00 112.06 112.90 113.80 115.00 116.20 117.00 118.00 120.00 120.00 120.00>You should read up on 'indexing' in the R Intro paper.
