I have model-data named as: model that is split as model.T(train) and
model.V(test or validation). The least square model (from lm to step) is built
withmodel.T and I like to see how model.T is robust by comparing predicted
model.V toactual model.V. How do I get score for model.V based on model
I am doing the data transpose with rename as shown below (step1 ~ step4)
1. Is any way in R similar to PROC TRANSPOSE used in SAS?2. How to use
MACRO-LOOP to simplify the following procedure?
THANK YOU FOR HELPS!
# create data for test
x<-data.frame(
a=c(1,2,3),
b=c("1","2","3"));
x; str(x)# s
or helps!

Right! the following works to r but not sqldf.
MVAR <- "population"
tab[[ MVAR ]]
sqldf("select tab[[MVAR]] from tab")

In the following r-program, for instance, I cannot use ... tab$MVAR...or simply
MVAR itself since MVAR is defined as "population" with double quotes if using
MVAR<-c("population")

There is a %LET statement in SAS: %let MVAR=population; Thus, MVAR can be used
through entire program.
In R, I tried MAVR<-c("population"). The problem is that MAVR comes with double
quote "" that I don't need. But MVAR<-c(population) did NOT work out. Any
way that double quote can be remov

Any advice for the following errors?
state.map <- readShapeSpatial("maps/st24_d00.shp")
Error in getinfo.shape(fn) : Error opening SHP file

Hi All,
I am new here and a beginner for R. Can I use SQL procedure in R environment as
it can be done in SAS starting with PROC SQL;
Thanks for helps!
