[R] Creating an R package in windows- where to put images?
My R version: 2.15.1- windows While creating an R package in windows, i want to include an image (a .gif image) that will finally be in the package. A function in my package will call the gif image. Where should i put the images before running Rcmd build mypkg or Rcmd INSTALL --build mypkg, so that after creating the package, the .zip file / .tar.gz/ .tgz would have the gif image in the correct place in each OS. Basically two questions (1) which directory should i put the gif image before building the pkg and (2)how do i specify the path in the function that will call the gif image?

[R] Error msg in rpanel
I am working on the r panel package. Now if i have a function that uses a
radiogroup button, and if i attempt to run the function from inside the
rpanel menu, i get this error:
Error in panel$intname : $ operator is invalid for atomic vectors
However if i run the function per se i.e. not from inside the rpanel
menu, but by calling it independently, the above error doesn't appear.
Here is a simple example. Try running the whole code versus just
running the add() function. The former results in the above error and
the latter doesn't.
install.packages(c(rpanel,tkrplot))
my.menu - function(panel) {
library(rpanel,tkrplot)
if (panel$menu==Add){
add()
}
else
panel
}
main.panel - rp.control(title = Main Menu,size=c(200,150))
rp.menu(panel = main.panel, var = menu,
labels = list(list(Addition, Add)),
action = my.menu)
# function to do adddition
add - function(){
my.draw - function(panel) {
if(panel$vals==numbers){
val-as.numeric(panel$nmbr1)+as.numeric(panel$nmbr2)
}
else if(panel$vals==strings){
val - paste(as.character(panel$nmbr1), and ,as.character(panel$nmbr2))
}
plot(1:10, 1:10, type=n, xlab=, ylab=,
axes=FALSE, frame = TRUE)
text(5, 5, paste(Result: , val),cex=1.4)
panel
}
my.redraw - function(panel) {
rp.tkrreplot(panel, my.tkrplot)
panel
}
my.panel - rp.control(title = Addition)
rp.textentry(panel = my.panel, var = nmbr1,
labels = First: , action = my.redraw, initval=100)
rp.textentry(panel = my.panel, var = nmbr2,
labels = Second:, action = my.redraw, initval=200)
rp.radiogroup(panel = my.panel, var = vals,
values = c(numbers, strings),
action = my.redraw, title = Type)
rp.tkrplot(panel = my.panel, name = my.tkrplot, plotfun = my.draw)
}

[R] How to display result of a calculation within panel
How do i make rpanel print the value of a calculation in the rpanel itself
- in a space just below the submit button?
The calculation uses user inputs (using rp.textentry) and takes the values
entered as input to the function via function (myRpanel)
e.g.
myfunction - function(myRpanel){
z- myRpanel$x + myRpanel$y
return(z)
}
myRpanel - rp.control(My new function)
rp.textentry(myRpanel, x, myfunction, x :, initval = 20)
rp.textentry(myRpanel, y, myfunction, y :, initval = 10)
rp.button(myRpanel, title = Submit, action = myfunction)
Thank you
Subramanian

[R] How to Get option prices of first date and expiry date alone
i have option prices of 1 month option contract for several days in a csv file. The data is in chronological order of dates. Within each date, price quotes for each strike appears (about 30 strikes per month- so there are in 30 rows per day for many days and many months). i want only the quote on the first date of the month (when the options are introduced) and on the last Thursday of the month or the previous day if the last Thursday is a holiday (i.e. the date when the options expire). i want the rows for all strikes for only these two dates alone (i.e. 30 begin date of each month + 30 rows expiry date each month) for all months in my data. Please guide.

[R] installing packages from a directory on the computer
Peter, i tried the file.choose() method of installing from local zip files;
its easy to install few packages that way. but you see if there are many
packages(say 10 or 12), then i wont be able to install the packages on
which the packages that i want to install depend because i guess i cant set
dependencies=TRUE by this method.
here is what i tried
i replaced http://my.local.cran; (code below) in Rprofile.site with
file://C:/R/packages/ and then did
install.packages(c(pkg1, pkg2, ...),dependencies=TRUE) in R console but
dint succeed..
# set a CRAN mirror
local({r - getOption(repos)
r[CRAN] - http://my.local.cran/;
options(repos=r)})
Would Appreciate help

[R] Installing packages from folder on the computer
i am able to install zip files of packages from local zip files using the
file.choose() for the package argument in install.packages() function in R
console and also from the Packages menuinstall from local zip files. But
if there are many packages to install (say 15 or 20), then i have to factor
in dependencies of 15-20 packages which may be more than 100 or 200 packages
in all to be installed. i'd have to go and choose so many of them.
so, i want a command line solution.
here is what i tried:
following the CRAN Miror's hierarchy of the directory where package zip
files are, i have put zip files of packages in:
C:\R\packages\bin\windows\contrib\2.11
To set this folder as my Mirror to install packages from, in Rprofile.site i
replaced http://my.local.cran; with file://C:/R/packages/ (full code
given below) and then in R console i enter:
install.packages(c(pkg1, pkg2, ...),dependencies=TRUE)
but dint succeed.
Error message: Warning in gzfile(file, r) :
cannot open compressed file
'//C:/R/packages/bin/windows/contrib/2.11/PACKAGES', probable reason 'No
such file or directory'
Error in gzfile(file, r) : cannot open the connection
# code in Rprofile.site to set a CRAN mirror
local({r - getOption(repos)
r[CRAN] - http://my.local.cran/;
options(repos=r)})
have changed this to:
local({r - getOption(repos)
r[CRAN] - file://C:/R/packages/
options(repos=r)})
Pls help.
