Honestly, your original question is rather vague and leaves us to  
guess (i) what you're trying to do, and (ii) how to help.

For example:


col<-c(23:28)

#Setup
for(k in col){
Initial.State(Response=zample[,c(k,29)],
Explanatory=zample[,variable_columns],
IndependentResponse=population[,c(k,29)],
IndependentExplanatory=population[,variable_columns])

#Modeling
Models(GLM=T, GAM=T, RF=T, GBM=T, TSS=T, KeepPredIndependent=T)
}

Your for loop is correct and should iterate 6 times, and k is getting  
vals 23 to 28:

You say that this code stops after the first model is complete, but if  
all goes well, it really shouldn't, eg:

===
col<-c(23:28)
for(k in col) {
cat(k, ' ')
}

Prints:
23  24  25  26  27  28  >
===

This means R should be giving you some type of error message and w/o  
telling us more, we're left to take stabs at the dark, which isn't a  
goof use of anybody's time.
