I am trying to correlate multiple variables within a dataset.
The dataset I'm using is gayreshaped.csv.
First, I filtered the "study" and "treatment" variables:
gayreshaped3 <- filter(gayreshaped, study == 2, treatment == "No Contact")
After that, I tried to correlate the "therm1", "therm2", "therm3" and "therm4" variables but I couldn't get a result.
I am trying to use this command but it is not working.
gayreshaped3therms12 <- cor(gayreshaped3$therm1, gayreshaped3$therm2, gayreshaped3$therm3,gayreshaped3$therm4, use = "pairwise.complete.obs")
It also gave me this error: "Error in match.arg(method) : 'arg' must be NULL or a character vector"
Is there another way to correlate them or to solve this NULL problem?
