[R] olsrr and substitute lm -> lmRob

2023-10-10 Thread Ashim Kapoor 
Dear all,

I wish to use backward selection from the package olsrr.
?ols_step_backward_p
This gives me a model of class lm.
I wish to then run lmRob from the robust package on the SAME variables
ie I want to substitute lm -> lmRob in the function call which created
the lm model.

Here is a reprex:

library(olsrr)
library(robust)

myformula <- lm(mpg~.,data = mtcars)

# This is how I do backward selection.

chosen.model = ols_step_backward_p(myformula,details=F)

# Chosen model

chosen.model$model

# Not sure if this is the correct thing to do

lmRob(chosen.model$model)

--

My query is : is the above correct ? Do I need to do some meta
programming and substitute lm with lmRob ?
I am not sure how I would do that in this context using the
?substitute function perhaps ?

Many thanks,
Ashim

Do you have anything valuable stored in /Users/admin/.RData? Does the
message disappear if you move the file away?

If you don't get your problem solved here, try asking at
r-sig-...@r-project.org.

Thank you for doing that! This is exactly the right thing to do.

[R] Problem with compatible library versions

2023-10-10 Thread Sabine Braun 
On the github website I have reported several bugs with new versions of 
the tidyverse group (probably dplyr) which prevent me from using R 
normally. I wanted to go back to older versions but this seems not bo be 
easy. I downloaded R 4.1.2. and Rtools 40 but the library versions 
installed are still the newest ones. I was able to install dplyr 1.0.7. 
manually but there are error messages on incompatibility when loading 
this version. Is there a possibility to load older library versions 
which alre compatible ?

Thank you very much!

Best regards

Sabine Braun
