I encountered some weird behaviour with readLines() recently, and I am

issue is as follows:
If I have a text file where a line ends with just a carriage return (\r, CR)
while the next line is empty and ends in
ice1 = paste0(var, '1_price'),
price2 = paste0(var, '2_price'),
volume1 = paste0(var, '1_volume'),
volume2 = paste0(var, '2_volume')

Christofer,
Given the constraints you mentioned—bounded parameters, no intercept, and a sum
constraint—you're outside the capabilities of most off-the-shelf ordinal
logistic regression functions in R like vglm or polr.
The most flexible recommendation at this point is to implement c

The lm class in base R uses a "constructor computes and methods retrieve
results" approach... which isn't quite as flexible as a transformer approach
but still hides the gory details.

Hi R team!
Since last Friday 04/04, my team and I have faced an error with running
the 'get_acs()' command from the tidycensus package. The code we ran and the
error message we received are shown below. Our troubleshooting efforts showed

there are ways to implement constraints on parameter estimates in ordinal
logistic regression in R. Here are a few approaches:
The rms package (Regression Modeling Strategies) by Frank Harrell offers the
lrm function which can handle constraints through its penalty parameter, though

Hello, all,
We're now starting to cover hypothesis tests in my Stats 101 course. As
usual in courses using the Lock5 textbook, 3rd ed., the homework
answers are calculated using their StatKey application. In addition
(and for no extra credit), I'm trying to solve the problems using R. I
Dear R-experts,
Here below a toy example not working. After some researches on the Net, still
don't get it !
Many thanks for your precious help.
