Calling a column from a matrix using a variable
Hi there,
I'm having some difficulty using a variable to call a column from a matrix.
I am trying to analyze several columns against each other using a for loop
in the following way:
x<-data.frame(A=1:5,B=6:10,C=11:15,D=16:20,E=21:26)
titles<-c("A","B","C","E")
for( i in 1:length(titles)){
y<-titles[i]
