替换 R 中一个单元格上的日期值

Question

I would replace the date value in a single cell, but I didn't find the way to do...

## dataframe = these_ac
## Anonymat = one of the variables
## these_ac$Anonymat == 17725 : the ligne I want to select
## entree = a date variable

these_ac[these_ac$Anonymat == 17725, "entree"] <- 1993-03-22 

Answer 1

these_ac["entree"][these_ac["Anonymat"] == 17725] <- "22/03/1993"

I think it's one way to do this.

It works in my case.
