Hi,
For example, the data.frame like:
origdata.long <- read.table(header=T, con <- textConnection('
subject sex condition measurement
1 M control 7.9
1 M first 12.3
1 M second 10.7
2 F control 6.3
2 F first 10.6
2 F second 11.1
3 F control 9.5
3 F first 13.1
3 F second 13.8
4 M control 11.5
4 M first 13.4
4 M second 12.9
'))
close(con)
Given a vector c('first', 'second', 'control), how can I reshape the
data.frame to this?
# subject sex first second control
# 1 M 12.3 10.7 7.9
# 2 F 10.6 11.1 6.3
# 3 F 13.1 13.8 9.5
# 4 M 13.4 12.9 11.5
I know reshape() can transform the data.frame from long to wide, but it
seems not able to control the order of the columns.
Thanks ahead of time
