I try to perform the function cbind as follows:
reg<-lm(cbind(variable1,variable2,variable3,variable4,variable5,variable6)~kmeans,data=dataset)
and it works.
But consider this structure:
vars<-names(dataset)[1:6]
vars
#[1] "variable1" "variable2" "variable3" "variable4" "variable5" "variable6"
reg<-lm(cbind(vars)~kmeans,data=dataset)
returning:
Error in model.frame.default(formula = cbind(vars) ~ kmeans, data = dataset, :
variable lengths differ (found for 'kmeans')
I tried that too:
reg<-lm(cbind(dataset[,c(1:6)])~kmeans,data=dataset)
but makes a mistake.
dput for assistance in response:
