用 0 和 1 替换 r 中的所有文本字符串

Question

I am working on a school project. My df contains a lot of character strings. Would I would like to do for my regression analysis is to replace any row that has a string with 1 to imply that yes something happens and any row that is blank with 0 to imply that there is nothing there. For instance, a column is called indigenous and has many different language types for people that speak non common languages but for those that just speak english it is blank. What i would want to do is that for any column that is filled make it a 1 and any column that is blank make it a zero.

Answer 1

Maybe you can try nzchar , eg,

> +nzchar(s)
[1] 1 0 1

Data

s <- c("abc","","volvo")
