I am trying to use the value of an ID variable in an if statement and
not getting the results I expected.
# ID values for two school districts
> with(rf, tapply(DistrictID, DistrictName, min) )
Aberdeen School Dist. # 58 Buhl Joint School District
59340 53409
This creates DNAME as I expected ...
rf$DNAME[rf$DistrictID==59340] <- 'Aberdeen'
rf$DNAME[rf$DistrictID==53409] <- 'Buhl'
> with(rf, table(DistrictName, DNAME) )
DNAME
DistrictName Aberdeen Buhl
Aberdeen School Dist. # 58 242 0
Buhl Joint School District 0 428
But these if statements ...
if(rf$DistrictID == 59340) {rf$D.NAME <- 'Aberdeen'}
if(rf$DistrictID == 53409) {rf$D.NAME <- 'Buhl'}
Lead to this ...
with(rf, table(DistrictName, D.NAME) )
D.NAME
DistrictName Aberdeen
Aberdeen School Dist. # 58 242
Buhl Joint School District 428
What am I doing wrong in the if statement?
Thanks!
