Hello list,
my first post but I've been using this list as a help source for a while.
Couldn't live without it.
I am writing a function that takes a dataframe as an argument and in the
end I intend to assign the result of some computation back to the
dataframe. This is what I have so far:
myFunction <- function(x){
y <- x[1,1]
z <- strsplit(as.character(y), split = " ")
if(length(z[[1]] > 1)){
predictedWord <- z[[1]][length(z[[1]])]
z <- z[[1]][-c(length(z[[1]]))]
z <- paste(z, collapse = " ")
}
x[1,1] <- z
}
And lets say I create my dataframe like this:
test <- data.frame(var1=c("a","b","c"),var2=c("d","e","f"))
and then call
myFunction(test)
The problem is when I assign x[1,1] to y in the first operation inside the
function, x becomes a dataframe inside the function scope and loses the
reference to the dataframe "test" passed as argument. In the end when I
assign z to what should be row 1 and column 1 of the "test" dataframe, it
assigns to x inside the function scope and no modification is made on
"test".
I hope the problem statement is clear.
Thank you,
Bernardo Doré
