Perhaps you can try this,
d <- c(0.00377467, 0.00377467, 0.00377467, 0.00380083,
0.00380083, 0.00380083,
0.00380959, 0.00380959, 0.00380959, 0.00380083, 0.00380083,
0.00380083)
c( t( cbind(matrix(d, ncol=3, byrow=T), 0)))
I don't know how to avoid the transpose operation that might slow
things down in large cases.
Hope this helps,

How about this:
dat<-
c
(0.00377467,0.00377467,0.00377467,0.00380083,0.00380083,0.00380083,0.00380959
,
+ 0.00380959,0.00380959,0.00380083,0.00380083,0.00380083)
dat[seq(1, by=3, to=length(dat))] <- 0
dat
[1] 0.00000000 0.00377467 0.00377467 0.00000000 0.00380083 0.00380083

Hi,
I have a vector that look like this:
dat
V1 V2 V3 V4 V5 V6
0.00377467 0.00377467 0.00377467 0.00380083 0.00380083 0.00380083
V7 V8 V9 V10 V11 V12
0.00380959 0.00380959 0.00380959 0.00380083 0.00380083 0.00380083
what I want to do is to insert 0 (zero) for every 3 position
yielding:
V1 V2 V3 V4 V5 V6
V7 V8
0 0.00377467 0.00377467 0.00377467 0 0.00380083 0.00380083
0.00380083
V9 V10 V11 V12 V13 V14
V15 V16
0 0.00380959 0.00380959 0.00380959 0 .00380083 0.00380083 0.00380083
Is there a quick way to do it in R?
