I have a dataframe in R
as follows
df <-
as.data.frame(cbind(c(1,2,3,4,5), c(0,1,2,3,4,5),c(1,2,4,5,6)))
and I have a function in which I want the procedure to stop and display a message if the input df
contains at least one 0 value. I tried the following but can't make it work properly. What is the correct if()
statement I should use?
my_function <- function(df){
if (all(df == 0) == 'TRUE')
stop(paste("invalid input df"))
}
CodePudding user response:
We could use %in%
my_function <- function(df) {
if(0 %in% unlist(df)) {
stop("invalid input df")
}
}
