Hi,
As was mentioned in another reply, you will not get formal legal advice here,
as none of us are intellectual property (IP) lawyers, and there can even be
country specific issues when it comes to such things, based upon local laws and
legal precedents that may be relevant.
That being said,

As far as I can tell, only the first day is selected randomly from your

consecutive days from the first day, for a total of 25 consecutive days.
Thus, all you need to do is to randomly select 1 day

Hi Guys,
I suspect that this entry from news() for 3.6.0 is relevant:

Always a good idea to read the NEWS file with a x.y point release. Peter
Wolfgang,
Perhaps I am missing something here, but with clogit(), or Heather's initial

'strata' argument need to be able to accept a nested structure, along the lines
of strata(id / site)?
On the page that you link to
Hi Heather,
I would defer to the mixed models experts, but I think that the basic approach
using nested random effects seems to make sense.
I don’t know that there is a dependency of glmer()/lme4 on metafor for this
specific use case, but would defer to Wolfgang on that point.

Hi,
For the usual R text to date conversions, you need a complete date. Since you
are missing the day of the month in your source text, you would need to impute
that part before making the conversion.
Also, since you don't appear to need to worry about time of day, just use

You might want to look at ?shQuote, which wraps text in single quotes, if the

Hi,
You might want to become familiar with the ?str and ?dim functions, which can
help you identify the structure of the objects that you are passing to
colMeans().
In the first case, flights[2] is a data frame with a single column, so will
have two dimensions with a row and column structure.

A quick clarification:
The regular expression is a single quoted character vector, not a
character vector on either side of the | operator:
"MLH1|MSH2"
not:
"MLH1"|"MSH2"
The | is treated as a special character within the regular expression.
See ?regex.

Hi,
When you experience errors with a third party package like that, one of
the first steps to take is to review the results of CRAN testing on the
package. That is available via the "CRAN checks:" link on the package page:
https://cran.r-project.org/web/packages/XLConnect/index.html
That
Hi,
You are going to need to provide more information than what you have
below and I may be mis-interpreting what you have provided.
Presuming you are designing a prospective, three-group, randomized
allocation study, there is typically an a priori specification of the

Hi,
A search would suggest that there may not be an R function/package that
provides power/sample size calculations for the specific scenarios that
you are describing. There may be something that I am missing, and there
is also other dedicated software such as PASS
Hi,
Just to add some additional comments that may be helpful.
1. The CRAN repository policy here:

"Package authors should make all reasonable efforts to provide
cross-platform portable code. Packages will not normally be
Hi,
I presume that you mean RHEL 8, and not just RH 8?
In either case, there is a list specifically for using R on RHEL/Fedora
based Linux derivative distributions:

You should subscribe to that list and post your query there, as the
Hi Rich,
You don't show the actual code that you used, and I do not use ggplot,
but if you want to use RGB hex codes to define a color, you need to use
'#' as a prefix for the 6 character RGB code:
For example:
> plot(1:10, col = "FF3030")
Error in plot.xy(xy, type, ...) : invalid color

Hi,
You do not indicate your use case, and that can be important.

Hi,
Not sure where you have been looking, but on CRAN:

there is a box at the top of the main page to Download R for macOS,

Eric,
With respect to your second point, as one of the moderators for the
R-Devel list, where the same considerations apply to all "official" R
lists like R-Help here, the issue of plain text content restrictions is
multi-factorial, partly with security considerations in mind, but has
Hi Dennis,
I believe that it may be as simple as:
> format(Sys.time(), "%z")
[1] "-0400"
Where "%z" returns the offset from UTC as a character vector, and where I am in:
> Sys.timezone()
[1] "America/New_York"
There may be some subtleties, and I would suggest reading the relevant help

Hi,
You do not need to use third party packages for date or date/time objects in R.
If you review ?as.Date, you will see that there are two default formats for
Date objects that are specified in the 'tryFormats' argument:
tryFormats = c("%Y-%m-%d", "%Y/%m/%d")
If your date character vector
Hi,
You were on the right track using stack(), but you just pass the entire data
frame as a single object, not the separate columns:
> stack(NamesWide)
values ind
1 Tom Name1
2 Dick Name1
3 Larry Name2
4 Curly Name2
Note that stack also returns the index (second column of 'ind'
Hi,
You are using the prop_test() function from the infer CRAN package, with an
argument set for an example using the prop_test() function from the rstatix
CRAN package.
They are **not** the same function, and do not take the same arguments, even
though they have the same name.

Hi,
An additional resource that was not listed below is the R Software Development
Life Cycle (SDLC) document that is available here:
https://www.r-project.org/certification.html
which addresses a subset of the issues raised.
