Permanently set drop to FALSE for vector operators in R

Question

As stated in R documentation, the operator '[' is defined in this way:

x[i, j, ... , drop = TRUE]

Is there a way to redefine it in order to set drop parameter default value to FALSE?

Answer 1

`[` <- function(...) base::`[`(...,drop=FALSE)  

This should prevent some undesirable behaviour in R where a matrix that is reduced to one row or one column will suddenly behave like a c(number,number,number) instead of matrix(c(number,number,number),ncol=1)
