Thank Matt for your response.
Would be an acceptable solution to check if the variable exists first and
creating the new variable with a suffix? Please, see the following example
var_name <- "name"
var_name <- ifelse(exists(var_name),
paste(var_name, "_vct", sep = ""),
var_name)
and then
assign(var_name, 1, envir = .GlobalEnv)
Cheers,
Tiago
