data.frame, converting row data to columns
Does this do what you want:
x <- read.table(textConnection("name wrist nLevel emot
+ 1 4094 3.34 1 frustrated + 2 4094 3.94 1 frustrated + 3 4094 NA 1 frustrated + 4 4094 3.51 1 frustrated + 5 4094 3.81 1 frustrated + 6 4101 2.62 4 excited + 7 4094 2.65 1 frustrated + 8 4101 NA 4 excited + 9 4101 0.24 4 excited + 10 4101 0.23 4 excited"), header=TRUE)
# add index x$indx <- ave(seq_along(x$emot), x$emot, FUN=function(z) seq(length(z))) require(reshape) y <- melt(x, measure='wrist') cast(y, name+nLevel+emot~indx)
name nLevel emot 1 2 3 4 5 6 1 4094 1 frustrated 3.34 3.94 NA 3.51 3.81 2.65 2 4101 4 excited 2.62 NA 0.24 0.23 NA NA

I am trying to change it to this:
? ? ? ? ? ? ?name ? ? ? ? ?nLevel ? ? ? ? ? emot ? ? ? ? ?w1
w2 ? ? ? w3 ? ? ?w4 ? ? ?w5 ? ? w5
? ? ? ? ? ? ? ?4094 ? ? ? ? ? ? ? ? ? 1 ? ? ?frustrated ? ?3.34
3.94 ? ? ?NA ? ?3.51 ? ? 3.81 ? ?2.65
? ? ? ? ? ? ? ?4101 ? ? ? ? ? ? ? ? ? 4 ? ? ?excited
2.62 ? ? ? NA ? ? 0.24 ? ?0.23 ? ? ?NA ? ?NA
The nLevel and emot will never vary with the name, so there can be one
row per name. ?But I need the wrist measurements to be in the same
row. ?The number of wrist measures are variable, so I could fill in
with NAs . ?But I really just need help with reshaping the data frame
I think I had some success with the melt
x
=
melt
.data
.frame(bsub,id.vars=c("name","nLevel","emot"),measure.vars=c("wrist"))
But I can't figure out the cast to get the wrist values in the rows.
Thanks
