MASS in R commander

[Mr Nice Guy]

Hey guys having a little technical difficulty in R Commander.

The problem is I am unable to select "Basic Diagnostic Plots" after I import a dataset .csv file. When I click on the "Models" tab then go to "Graphs" it shows all the options but does not allow me to select any of them (basic diagnostic plots, residual-quantile comparison plots etc.)

I have been told that this is because I do not have MASS loaded, but I am unsure how to load MASS if it is indeed my problem. The MASS package is not listed when I go to "Tools"-"load package(s)."

Any thoughts? Thank you.

either go to install packages and select MASS or use:

install.packages("MASS")

if this doesn't fix the rcmdr issue, repost.

[Mr Nice Guy]

Thanks bugman. I gave the script a code and it did not appear to work but it says MASS is already loaded from what I gather? Here is the output:


> install.packages("MASS")
Installing package(s) into 'C:/Users/Mr. Nice Guy/Documents/R/win-library/2.15'
(as 'lib' is unspecified)
Warning: package 'MASS' is in use and will not be installed

Have you loaded MASS?

library(MASS)

I don't use R commander so I don't know if that's the problem or not...

[Mr Nice Guy]

When I go to the "Load Packages" menu, MASS is not an option.

[Dason]

Ok try this. Forget R Commander. Just load up R and see if calling library(MASS) works.

[Mr Nice Guy]

Well I was trying to install and load MASS from R commander. I found that I can load and install it in R. When I load MASS, no output is created so I am not sure if it worked or not. When I try to install MASS the out put is:


Warning: package ‘MASS’ is in use and will not be installed


I did input the command library(MASS) and it appeared to have no effect.

I am hoping to get a hold of my professor but communication with him is sketchy at best. Thanks everyone for the help i'll keep you guys updated if I can found out a way to make it work!

I did input the command library(MASS) and it appeared to have no effect.

So no protest from R. I think that means that the command worked.

Now run the rest of the commands (and maybe it works) .

[Dason]

Yes if you run library(MASS) and you don't see anything that means that you were able to successfully load the package. It doesn't make sense to try to install MASS right after you loaded it which is why you were getting the error.

I can't help with R commander problems because personally I don't like it and much prefer to just use the command line. But Greta I don't think they can run the rest of the commands because they don't appear to know what those commands are since they're trying to do everything with R Commander (which is a GUI add on)

[bugman]

I think its that your data are not loading properly. Try installing some of the plugins aswell and make sure your data set is imported properly then try and run an ANOVA, once you have done that the quantile quantile plots option wont be greyed out anymore and you will be able to select it. I dont think MASS is your problem.

[Mr Nice Guy]

Got it figured out.

My problem was I simply did not load the single factor ANOVA model first. It must be done before you check diagnostics.

Lol

They resolved the problem in the post above yours. Does that not work for you? Or is your problem different from theirs?
