similar to: .First.lib and namespaces

I'm creating a package for my own use that uses some S4 classes but no methods. I have a file called NAMESPACE it contains the line: exportClasses("foo") and at the top of the R file I have setClass("foo", representation(x="numeric") and the line: .onLoad<-function(libname,pkgname) When I run R CMD check I get Syntax error in the only R file. If I

Hi, I wonder whether a package with namespace & dynamic library can be installed with the version number attached, ie. with the argument --with-package-versions. Is this currently possible? Using R 1.9.1 on Debian 3.0 I encounter a problem when trying to load a package installed with R91 CMD INSTALL --with-package-versions -l /mnt/local/R/R-1.9.x-libs-EpiR RIO in R started with R91

Deepayan: Sorry for the additional email, but I'm concerned that I wasn't being clear. In the end, I would like a graphic that portrays my y-values on a log scale in their native data range. That is to say, I would prefer to see the axis labels as 1000 rather than 3 (log10 of 1000). Thank you for your kind assistance, Hobie Perry St. Paul, MN Hobie Perry <hobie_perry@yahoo.com>

No, there are lots of situations where that doesn't make sense. You don't want to have to define local copies of the functions from every package you use, for example. I think the takeaway is to learn how R scoping works, and keep things simple. That's one reason I tend to avoid "tidyverse" packages. There are a lot of really good ideas in those packages, but

Dear Duncan, THanks for the reply...! So the takeaway is that define the symbol in the same environment before using it right!?

Non-standard evaluation, used widely in formula-interface functions as well as the tidyverse. with() in my example is a less nuanced version of this. See

You can't change the basic way R searches, but you can ask for a different kind of search. For example, to see if "x" exists, you can use exists("x") and it will do the default search, but exists("x", inherits = FALSE) will only look in the current environment. The get() function has a similar argument which returns the value Unfortunately these

Hi, After a few modifications in the makefiles, I successfully compiled the Qt device (written by Deepayan Sirkar) for OS X 10.4.9 on a Powerbook. However when loading into R If i remove this line from zzz.R in qtutils/R grDevices::deviceIsInteractive("QT") and then install >library(qtutils) loads fine and the QT() calls returns a QT window, however, if i switch to

Dear Dr. Sarkar, When I try to run the codes, I found the following problem: > h<- sample(1:14, 319, rep=T) > c<- sample(1:14, 608, rep=T) > n<- sample(1:14, 1140, rep=T) > vt<-c(h, c, n) > ta<-rep(c("h", "c", "n"), c(319, 608, 1140)) > > to<-data.frame(vt,ta) > library(lattice) Attaching package: 'lattice'

Dear Deepayan, THanks for the pithy, pointed reply. But isn't it risky? Can I somehow get a warning when x is not defined in the global environment but takes on a value from one of the loaded packages? any packages for that?

Since we're on the topic of book reviews, I just received Phil Spector's new R book called "Data Manipulation with R" and it is also quite a nice book. I haven't gone through it all and I won't give a detailed review but I have gotten a lot out of the first 100 pages that I have read. Note that I've been using R for almost 1.5 years so , for me, it's a
