I am trying to run a moderation model in R but I don't have a lot of experience working with R and I struggle. I will appreciate any help and advise you can give me! I really want to learn. I am using Hayes model (model 1 / process) because all my variables are continuous. This is my code:
library(psych)
library(interactions)
library(rockchalk)
process(data = Prac, y = "no_After", x = "no_before", w = "FOMO", model = 1, center = 2, moments = 1, modelbt = 1, boot = 10000, seed = 12345)
And this is the error:
Error in desctmp[(4 + kd), jd] <- value : replacement has length zero
I Don't have any missing values, and I don't have any outliers. I updated and then restarted the R, and all my packages are updated too. I ended up creating another copy of the CSV file I have manually to see if this changes anything (didn't help). This is my data (It's not a lot because it's a beginners'' project in one of my classes):
> str(Prac)
'data.frame': 3 obs. of 4 variables:
$ Subject : int 101 103 119
$ FOMO : int 35 17 21
$ no_before: num 3.25 5.3 11.94
$ no_After : num 1.91 8.07 2.62
