How to test the difference between paired correlations?
Thank you, but this now sounds more difficult: what would be the point
in having these ready-made functions if I have to do it manually?
Anyway, How would I implement the last part?

Good Will Legal Question
My guess: It I clear from the link that they can use the R logo for commercial purposes. The issue is what to do about the "appropriate credit" and "link to the license." How would I do that on a hoodie? Would they need a web address or something?

Simple Stacking of Two Columns
I may be missing something but using the plain old c() combine function
seems to work fine:
df <- data.frame(left = 1:5, right = 6:10)
df.combined <- data.frame(comb = c(df$left, df$right))
df
left right
1 1 6
2 2 7
3 3 8
4 4 9
5 5 10
df.combined
comb
1 1
2 2
3 3
4 4
5 5
6 6
7 7
8 8
9 9

Sorry about that, let me check the correct version for the intrin0.h include guard.

Simple Stacking of Two Columns
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' values), which tells you which column in the source data frame the stacked values originated

naming datasubsets in a loop
Hello everbody,
I want to generate different subsets of my data-set and safe this
subsets with names listet in a vector. Because in reality I have got
about 70 subsets I want to realize this in a loop
Somehow like this:

Just to repeat:
you have
NamesWide<-data.frame(Name1=c("Tom","Dick"),Name2=c("Larry","Curly"))
and you want
NamesLong<-data.frame(Names=c("Tom","Dick","Larry","Curly"))
There must be something I am missing, because
NamesLong <- data.frame(Names = c(NamesWide$Name1, NamesWide$Name2))

apply
It's still hard to figure out what you want. If you have two vectors
you can compute their (2x2) covariance matrix using cov(cbind(x,y)).
If you want to compute all pairwise squared differences between elements
of x and y you could use outer(x, y, "-")^2.
Can you explain a little bit more about (1) the context for your
question and (2) why you want/need to use apply() ?

question
Hi guys,
I am using the cor() function to see if there are correlations between March cortisol levels and December cortisol levels and I'm trying to figure out if the function is doing what I want it to do.
Each sample has it's own separate row in the CSV file that I'm working out of. March Cort and December Cort are different columns and they come from separate samples, therefore

Convergence in geese/gee
We are currently analyzing data on children clustered in day care-centers (DCC). We have tried to use geepack and gee libraries to estimate an overall incidence rate for absences (=number of absences/risk time) by specifying

Citation for stock price data from Quantmod
Fair enough. You do not put citations in the abstract or summary. The level of detail in the methods can be modified by including a link to a repository or by including supplemental material, or appendix, or foot notes, or something equivalent. If all programs/packages are used with system defaults the version number is sufficient. If the packages are customized and such customization materially

Misc patches
Hi,
Here are 3 suggested patches.
1. Build test for cmake and run the test in gitlab-ci.
2. Disable the message box on Windows on abort that cause test hangs in CI.
3. Build time improvement by removing unnecessary includes of stdio.h in production code and change to a lighter header intrin.h -> intrin0.h (windows only). Attached screenshot of measurement but it resulted in 14%

new function: twotailed.colors {base}
I suggest to add a new function to create a vector of
n ``contiguous'' colors with tails in two colors.
This function is similar to `cm.colors' but the colors
can be choosen by hsv values.
This function could be used e.g. as alternative to
the default ``col.regions'' in `levelplot'.
Perhaps the arguments in the following code could be
simplified.

Base R wilcox.test gives incorrect answers, has been fixed in DescTools, solution can likely be ported to Base R
While using the Hodges Lehmann Mean in DescTools (DescTools::HodgesLehmann),
I found that it generated incorrect answers (see
<https://github.com/AndriSignorell/DescTools/issues/97>
https://github.com/AndriSignorell/DescTools/issues/97). The error is driven
by the existence of tied values forcing wilcox.test in Base R to switch to
an approximate algorithm that returns incorrect results - see

Citation for stock price data from Quantmod
The _point_ is to explain the story of the research so people can compare easily with other work. A story interrupted by tedious details is not very comprehensible. And I _did_ recommend providing a link to a code repository and using reproducible coding tools.

DescTools::Quantile
It looks like a homework assignment. It also looks like you didn't read the documentation carefully enough. The 'len.out' argument in seq is solely for specifying the length of a sequence. The 'quantile' function omputes the empirical quantile of raw data in the vector 'x' at cumulative probabilit(y)(ies) given in the weights' argument, with interpolation I'm

Errors in wilcox family functions
Hi Everyone,
Following the previous discussion on optimizing *wilcox functions, Andreas Loeffler brought to my attention a few other bugs in `wilcox` family functions. It seems like these issues have been discussed online in the past few months, but I haven?t seen discussion on R-devel...unless I missed an email, it seems like discussion never made it to the mailing list. I haven?t seen any bug
