The three routines in R that calculate the wilcoxon signed-rank test give different p-values.......which is correct?
I have a question concerning the Wilcoxon signed-rank test, and
specifically, which R subroutine I should use for my particular dataset.
There are three different commands in R (that I'm aware of) that calculate
the Wilcoxon signed-rank test; wilcox.test, wilcox.exact, and
wilcoxsign_test. When I run the three commands on the same dataset, I get
different p-values. I'm hoping that

Format Data Issue??
R Users,
I am new to R and have tried to figure out how to automate this
process instead of using excel. I have read in this dataframe into r
with read.table. I need to reshape the data from the first table into
the format of the second table.

R Profiling
Dear All,
I need to do some very basic R profiling, something along the lines of:
run this whole script five times and return the average completion time.
I do not want (at this stage) delve into the details of the percentage
of the time spent in which function and doing what.
Which tools should I use?
Any recommendation is welcome.
Best Regards

is this matrix symmetric
Hi,
I have this symmetric matrix, at least I think so.
col1 col2 col3
[1,] 0.20 0.05 0.06
[2,] 0.05 0.10 0.03
[3,] 0.06 0.03 0.08
or
structure(c(0.2, 0.05, 0.06, 0.05, 0.1, 0.03, 0.06, 0.03, 0.08
), .Dim = c(3L, 3L), .Dimnames = list(NULL, c("var1", "var2",
"var3")))
But isSymmetric() doesn't agree. Any comment? I am on R 2.10.1 Thanks.

Going back to the "prioritizing aggregated DBs" thread from
February 2020, I've got 390 Xapian shards for 130 public inboxes
I want to search against(*). There's more on the horizon (we're
expecting tens of thousands of public inboxes).

the actual queries seem to be taking ~30s (not good :x).

read.table performance
** Disclaimer: I'm looking for general suggestions **
I'm sorry, but can't send out the file I'm using, so there is no
reproducible example.
I'm using read.table and it's taking over 30 seconds to read a tiny file.
The strange thing is that it takes roughly the same amount of time if the
file is 100 times larger.
After re-reviewing the data Import / Export manual I think

Help interpreting output of Rprof
Hello there,
I am not quite sure how to interpret the output of Rprof (in the following the output I was staring at). I was poking around the web a little bit for documentation but without much success. I guess if I want to figure out what takes so long in my code the 2nd table $by.total and the total.pct column (pct = percent) is the most helpful. What does it mean that [ or [.data.frame is

randomForest gives different results for formula call v. x, y methods. Why?
Just out of curiosity, I took the default "iris" example in the RF
helpfile...
but seeing the admonition against using the formula interface for large data
sets, I wanted to play around a bit to see how the various options affected
the output. Found something interesting I couldn't find documentation for...
Just like the example...

LOOping problem with R
Dear Guys,
I do converting codes from Fortran into R and got stuck in solving LOOPING
procedure with R. In FORTRAN, it is (DO and END DO) for looping in the net.
In R, it is (FOR with { }).
I believe there is something wrong with my coding in R, do hope that you can
help me solving following problems.
It seems easy, but results are not the same.
