Hi Antony,
Try this,
I changed matrix to data frame to make it work and change it back again to
matrix. There might be a easy way to do this.
GetCsv<-as.matrix(data.frame("DWATT"=c(10,20,30,30,32)))
GetCsv<-data.frame(GetCsv)
GetCsv[GetCsv$DWATT<30 | GetCsv$DWATT >31, "DWAT_QF"] <-"RC"
GetCsv[is.na(GetCsv)]<- ""
GetCsv
DWATT DWAT_QF
1 10 RC
2 20 RC
3 30
4 30
5 32 RC
GetCsv<-as.matrix(GetCsv)
GetCsv
DWATT DWAT_QF
[1,] "10" "RC"
[2,] "20" "RC"
[3,] "30" ""
[4,] "30" ""
[5,] "32" "RC"
A.K.

Subject: [R] Create and Change Column in a Matrix as per condition
Hi,
i have a matrix like this
*DWATT *
10
20
30
30
32
Here i need to create a new column named "*DWATT_QF*" with filling value as
per the following condition,
if DWATT_QF = RC When DWATT value less than 30 and greater than 31. Which
means, i need output like this,
*DWATT DWATT_QF*
10 RC
20 RC
30 RC
30 RC
32 RC
Here " GetCsv " is my matrix name. i tried this way and its getting proper
in "R",
GetCsv[(GetCsv[,ColHdr]< 30) | (GetCsv[,ColHdr]>31),ColHdr_QF]<-"RC"
But i *not getting in Eclips*, and getting error like "*Sub script Out of
Range*"
Could you please help me fast. Its an urgent !
- Thanks
Antony
