# Here's where I extract the database IDs and repeat them 50 times to make the column long enough for | |
# my new long-form dataset (596,100 rows) | |
client.data.new = rep(client.data[,1],50) | |
for (i in 2:32){ | |
# for each column in the first 31 after the ID column, find the 49 matching columns | |
# to the right and stack them using melt | |
stacked.data = melt(client.data, id.vars="CnBio_ID", measure.vars=seq(i,(i+(31*49)),31), value.name=names(client.data)[i]) | |
# Once we have one new stacked column, we add it on to the right of whatever has already been built in the | |
# new long-form dataset. | |
client.data.new = data.frame(client.data.new, stacked.data[,3]) | |
} | |
# I don't know why the "value.name" argument didn't give me the right variable names for my | |
# new long-form dataset, but it was easy enough to use this last line of code to fix that! | |
