Hi Suhaila,
You don't need to make a function: your script should just contain:
med <- read.csv("medicalData.csv")
If you do want to make a function, then you need to assign the
resulting value to something, eg:
med <- readData()
but there's no reason to do that. Values that are assigned within
R is a functional language so, by default, assignments (and other
things) within function scope doesn't have global effects. This is
generally considered a _very good thing_ in language design. You'd
perhaps prefer something like:
readData <- function() {
read.csv("medialData.csv")
}
med <- r
Hello. I'm a newbie here.
In my script (I name it readData.R), I wrote the followings:
readData <-function(){ med = read.csv("medicalData.csv");}
Then I tested the script by 'Source R Code' then on the command I typed
'readData()' then I typed 'med' to check if the variable contains the medical
5 matches
