Hi all:
I solved the previous stated problem in something of a brute force way
(but it works). I seem to now be running into one little hiccup using
reshape. Here is a quick snip of the data in long format:
grade stability year schid
6 Grade 4 3 2001 100005
7 Grade 4 3 2002 100005
8 Grade 4 2 2003 100005
10 Grade 5 2 2001 100005
11 Grade 5 2 2002 100005
12 Grade 5 1 2003 100005
18 Grade 4 2 2001 100010
19 Grade 4 2 2002 100010
20 Grade 4 2 2003 100010
22 Grade 5 2 2001 100010
Now, I want to reshape this into the wide format. However, when I do I
get NAs in the stability columns. Here is what I have done and the
result.
wide<- reshape(tennshort, idvar = c("schid","grade"), timevar = "year",
v.names="stability", direction="wide")
grade schid stability.2001 stability.2002 stability.2003
6 Grade 4 100005 NA NA NA
10 Grade 5 100005 NA NA NA
18 Grade 4 100010 NA NA NA
22 Grade 5 100010 NA NA NA
What appears to be the reason I get NAs in the newly created stability
columns?
Thank you
Harold
