R data file

R datasets, with their data correctly formatted, can be specified directly to Facets.

Data= Rdataset.rda

Dvalues= is useful for constant values in the data

 

Here is an example of data in an R data file.

 

Please edit Guilford.txt so that the following specifications are not commented ";"

 

dvalues = 3, 1-5

data = Guilford.rda ; R file omitting 1-5 for the 3rd facet

 

Comment ";" all the other data= specifications.

 

Launch Facets and analyze Guilford.txt. You should see:

First active data line is: 1,1,5,5,3,5,3

             Processed as: 1, 1, 1_5, 5,5,3,5,3

>=============================================================================<

Total lines in data file = 22

Total data lines = 22

Responses matched to model: ?B,?B,?,CREATIVITY,1 = 105

 

If the data appear to be incorrect, verify that Facets has imported your R Statistics  data file correctly, look at the temporary "Data =" file in the Edit pull-down menu.

 

 

We see a text-format version of the R file. The values are comma-separated.
