The RStudio editor itself is pretty mediocre. It is the context sensitive

Dear R-help,
I am trying to reproduce some results presented in a paper by Anderson
and Blundell in 1982 in Econometrica using R.
The estimation I want to reproduce concerns maximum likelihood
estimation of a singular equation system.
I can estimate the static model successfully in Stata but for t

Hi all,
An R blogger just published a comparison between R and stata for performing:
- Multinomial Logit
- Proportional odds model
- Generalized Logit

spatstat::nndist calculates Euclidean distances rather than distances

Can anyone tell me why I would get different average nearest neighbor values

R-helpers,
I am hoping to find someone who uses both R and program Stata for GLMs.
I am a beginner R user, finding my own way through; learning code etc. at the
same time as learning the statistics I need to complete my project.
What I have is the code from Stata and am trying to reproduce th
@all: Does it seem reasonable to add a discussion of '=' vs. '<-' to
the FAQ? It seems a regular question and something of a "hot" topic
to debate.
@KM Here are links I've accumulated to prior discussions on this
topic. I am pretty certain they are all unique.

Yes, mostly, you can also use 'help' to ask such questions:

The operators ‘<-’ and ‘=’ assign into the environment in which
they are evaluated. T
