I would like to create a function to convert data based on a class using
as.numeric
Similarly, using a plot, I do:
plot.essai <- function(x, ...) {return(x*2)}
d <- 10
class(d) <- "essai"
plot(d)
It works:
[1] 20
attr(,"class")
[1] "essai"
Now same w
Hello,
Actually, it's working as expected. 'numeric' is a class and the
function as.numeric() is doing what it should:
as.numeric.essai <- function(x, ...) {return(x*2)}
d2 <- as.numeric(d)
class(d2)
[1] "numeric"
Maybe you want an as.essai function.
as.essai <- function(x, ...) {x <- as.num
2 matches
