Re: [R] For loop with multiple iteration indexes
Thank you everyone. After thinking about each response, I realized a fairly
simple solution is available (obviously, other suggested approaches work as
well):
stopifnot(length(x) == length(y); stopifnot(length(x) > 0)
r <- list()
for (i in 1:length(x) ) {
r[[i]] <- cor(x = dat[, x[i] ], y = dat[, y[i] ])
}
print(r)

Re: [R] Why can't I make use of tcltk in this installation?
Hello Albrecht.
I didn't specify those paths on the 3 machines that have tcltk
available. It appears that those files are not on the machine in
question and that is the reason for my problem. But if they are,
./configure finds them itself.
I'm not at the machine that has the issue, but I assume that since I get
this on a machine that does work:
dpkg -S tkConfig.sh
tk8.6-dev:amd64: /usr/lib/x86_64-linux-gnu/tk8.6/tkConfig.sh
tk8.6-dev:amd64: /usr/lib/tk8.6/tkConfig.sh
tk-dev:amd64: /usr/lib/x86_64-linux-gnu/tkConfig.sh
tk-dev:amd64: /usr/lib/tkConfig.sh
I need to install those two packages (and the corresponding ones for
tcl) and reinstall R.
Thanks for the pointer, and thank you pd for drawing my attention to the
fact that Tcl and Tk need to be done separately.

That's the same as what I get on another computer on which tcktl is

Where else should I be looking for a difference?

Re: [R] Packaged exe and Shiny
IMO the best short answer is don't target making an install package or msi at all... the obstacles are quite significant. Aim for building most of your capabilities in packages and having people install them. You can setup an in-house package repo to simplify this and give them a startup script that configures their R environment. There is also the option to use R-Portable [1] but this leads to massive deployment files that don't upgrade easily. I also think that when the time crunch happens many people will go to the internet and copy-paste solutions that you would be unlikely to have anticipated. Closing off that scary console completely will keep you in the hot seat indefinitely, whereas giving them the option to go around your UI lets more resources be allocated later.

Re: [R] Packaged exe and Shiny
Hi Kevin, It might be just as easy to write R scripts that would do basic analyses. Users could "source" these scripts in an R session or from the command line. The scripts would be much more compact than the .exe files that you describe.

[R] Packaged exe and Shiny
Hey Everyone, I do not know if this topic has been covered, I'm sure it must have, but is there a good environment for packaging R code into a distributed exe. (which includes all of the required libraries, etc.)? I have seen that Shiny is a good GUI / Web library for sharing R programs, but I have never used it. What is the groups input on this? My goal is to create some basic tools (with interfaces) at work for analyzing .csv files and generating basic graphs and output csv files. These tools would be distributed to team members to have on their desktops. I considered doing this in Java, but I am more well versed in R so it would be quicker for me to whip up the varying tools in R than re-learning Java.

A more aRtful way (than a for loop) to approach this is with mapply:
i <- head(colnames(mtcars))
j <- tail(colnames(mtcars))
r <- mapply(function(i, j, dat) cor( x = dat[, i], y = dat[, j]),
i=i , j=j , MoreArgs = list( dat = mtcars),
SIMPLIFY = FALSE, USE.NAMES = FALSE)
and if you want, maybe USE.NAMES = paste(i, j, sep="_")

Re: [R] Why can't I make use of tcltk in this installation?
You may need to consult the R-sig-debian list, rather than R-help.
Offhand, I would expect that you need Tcl libraries, Tk libraries and the
associated -devel or -dev packages. Notice that although they are designed to
work together, Tcl and Tk are two separate entities, so searching for tcltk may
not suffice.

Hi Patrick,

That's the same as what I get on another computer on which tcktl is
available, so it didn't surprise me when installing the r-cran-tcktl
package didn't help.
Where else should I be looking for a difference?

[R] real time monitoring of streaming audio with R?
Hello, All: Is it feasible to do real time monitoring of streaming audio with R, writing a compressed copy of what's read to 1-hour long MP3 files? I'm a volunteer with a community radio station (kkfi.org). My minimum requirements at the moment are to create MP3 files from what we broadcast. I have a tuner hooked to the audio input of a computer. I can listen to it in real time using the computer audio output jack, and I can record it manually using Audacity. If I have MP3 versions of both what we send to the tower and what is actually broadcasted, I can read the two into R, compare them, identify substantive differences, write appropriate descriptions to files, send emails, etc. I don't know how to sample the live stream. I know it can be done in Python, but I don't know how, and I'd prefer to use R. I suspect it can be done with ffplay, part of ffmpeg, but again I don't know how.

Re: [R] For loop with multiple iteration indexes
Hi,
this simple example is very similarly, and it works in R:
r <- list()
n <- 0
x <- c("a","b","c")#x,y: Data from a dataframe
y <- c("A","B","C")
for (k in 1:3) {
n <- n+1
r[[n]] <- paste0(x[k],y[k])#or any other function using x[k] and y[k] as
arguments
}
print(r)
Is it this what you meant?
Best,
Albrecht
