Can you tell us what is wrong with the "chunked" package which comes up when you Google "r read large file in chunks"?

How to install rgeoda in R
The rgeoda maintainer seems to be having difficulty keeping up with required changes to be supported on CRAN. This may get corrected soon or never. There are instructions for compiling it yourself at https://geodacenter.github.io/rgeoda/ or you can contact the maintainer about their plans for getting it back on CRAN from there.

extracting pdf tables...
Clearly the column names are different. You need to decide what to do about that. Choose the subset of dataframes where the column names are the same? Rename columns? Omit some columns? Add missing columns filled with NA?

How to assign the same levels to a dataframe column?
Stop using as.factor() and start using factor()? Be explicit about what levels you want and in what order.
As for extracting subsets, use split() and do your subsets on each set of rows with the same level. It will be on you to decide what statistical properties (proportions?) you want to maintain between the full data set and your subset.

Help
Regarding 1 and 2, please read the Posting Guide mentioned at the bottom of every R-help post. R does not equal statistics... and education about statistics is way too ambitious to include in this mailing list that is about a tool that happens to be useful for statisticians.
There are forums online that do cater to statistical methods (e.g. Cross Validated or many results from a search engine)...

Even if this is not a homework question, it smells like one. If you read the Posting Guide it warns you that homework is off-topic, so when you impose an arbitrary constraint like "must use specific unrelated function" we feel like you are either cheating or wasting our time, and it is up to you to explain why we should follow you down this rabbit hole, keeping in mind that statistics

Then you don't have enough memory to process the whole thing at once. Not unlike stuffing your mouth with cookies and not being able to chew for lack of space to move the food around in your mouth.
Now, can you answer my question?

When you specify LE in the encoding type, you are logically telling the decoder that you know the two-byte pairs are in little-endian order... which could override whatever the byte-order-mark was indicating. If the BOM indicated big-endian then the file decoding would break. If there is a BOM, don't override it unless you have to (e.g. for a wrong BOM)... leave off the LE unless you really

A question on Statistics regarding regression
you say you asked elsewhere, but so many hits come up when I just search for "unbalanced sample size" your justification for not following the posting guide does not seem honest.
I also recall that various discussions of statistical power address this in basic statistics.

unable to plot bode - phase with control package
a) What is so difficult about the idea that this list is about R, not theory? There do exist forums about control theory (e.g. engineering.stackexchange.com)
b) Using [-pi,+pi) is not "wrong"... it is numerically more precise, though it may not convey what you would prefer to convey.

Extracting wind direction and wind speed from wind rose plot

ggplot two-factor legend
If I follow your question, you want redundant aesthetics. Ggplot normally notices correlated aesthetic mapping variables and merges the legends, so the most likely answer is that your data are not fully correlated in all rows. I have also seen this where data are drawn from different dataframes for different layers since it is hard to merge factors, but I don't see that here.

Reading a txt file from internet
I tried it on R 4.4.1 on Linux Mint 21.3 just before I posted it, and I just tried it on R 3.4.2 on Ubuntu 16.04 and R 4.3.2 on Windows 11 just now and it works on all of them.
I don't have a big-endian machine to test on, but the Unicode spec says to honor the BOM and if there isn't one to assume that it is big-endian data. But in this case there is a BOM so your machine has a buggy

adding "Page X of XX" to PDFs
One of the most fundamental characteristics of R programming is the use of data frames of column vectors, and one of the very first challenges I had as a then-Perl-programmer was coming to grips with the fact that unknown-length CSV files would be read completely into memory as rows and once the entire CSV was in memory it would be transposed into column vectors. I was resistant to this philosophy

Problems with installing R packages from source and running C++ in R, even on fresh R installation
TL:DR there are at least three maybe four ways to address this depending on what you plan to do.
I usually adjust PATH to add Rtools using .Rprofile. But if you do that then if you want to use the command line to invoke R then you need to set the PATH separately when you start the shell. For this reason some people like to set it in the User Environment Variables control panel... but some Rtools

missing() fails to detect missing
Fascinating. Or, well, not.
Failing to use a method signature that is compatible with the generic is a no-no. So your bug seems to me to be outside the bounds of how R is supposed to be used. So don't do that.

Posting Error. OP sent HTML email which by default includes a backup text version with "helpful" marks where formatting was in the original, and the mailing list deleted the HTML (per policy stated in the posting guide linked at the bottom of every email) which effectively leaves the mailing list recipients guessing as to what was originally sent.
