[R] reshape

[arun]

Hi,
You can try this:
dat1<-read.table(text="
Rad:0
Rad1:2
Rad3:3
",sep="",header=FALSE)


 Variable<-do.call(rbind,lapply(strsplit(as.character(dat1[[1]]),split=":"),`[`,1))
n11<-do.call(rbind,lapply(strsplit(as.character(dat1[[1]]),split=":"),function(x) as.numeric(x[2])))
 n12<-2400-n11
 dat2<-data.frame(Variable,n11,n12)
 dat2
#  Variable n11  n12
#1      Rad   0 2400
#2     Rad1   2 2398
#3     Rad3   3 2397
 str(dat2)
#'data.frame':    3 obs. of  3 variables:
# $ Variable: Factor w/ 3 levels "Rad","Rad1","Rad3": 1 2 3
# $ n11     : num  0 2 3
# $ n12     : num  2400 2398 2397

#or if you want it as a matrix:
 newmat<-do.call(rbind,strsplit(as.character(dat1[[1]]),split=":"))
 n12<-2400-as.numeric(newmat[,2])
 newmat2<-cbind(newmat,n12)
colnames(newmat2)[1:2]<-c("Variable","n11")
A.K.

Hi,

I have a R output that looks as follow:
Rad:0
Rad1:2
Rad3:3

I want to make a new matrix that looks like : sample size is 2400
Variable    n11  n12
Rad            0     2400-0=2400
Rad1          2       2400-2
Rad3  3      2400-3
 
Thanks a lot for your time and help:)
Best,Farnoosh Sheikhi
