similar to: problems with installation of packages

I am having a peculiar problem with installation of packages. I am trying to install the package "maptools". This is what I get. install.packages("maptools",depend=T) Warning in install.packages("maptools", depend = T) : argument 'lib' is missing: using /usr/local/lib/R/site-library Warning: unable to access index for repository

I want to read data from a number of files into R. Reading individual files one by one requires writing enormous amount of code that will look something like the following. **************** maptools:::dbf.read("wb-01vc.dbf")->dist1 maptools:::dbf.read("wb-02vc.dbf")->dist2 maptools:::dbf.read("wb-03vc.dbf")->dist3

I need to make weighted boxplots. I found that ggplot makes them. I would however like to label them with the boxplot statistics (the median, q1 and q3). In the boxplot function in r-base, I could output boxplot statistics and then write a text on the plot to place the labels. How would one do it with ggplot? Vikas

I installed R (R-2.4.1-win32.exe) on a new computer with Windows Vista and a 64 bit operating system (hp dv9000 with intel core t7200). The base R runs fine, but I can not get any of the packages to load. From within R I choose install packages choose a site then a package. I tried installing 2 packages and get similar errors (see below), I just copied and pasted lines from R. Can anyone

I want to add RMySQL and RODBC packages to my R installation on redhat linux box. The command install.packages gives following output.

If you multiply a matrix by its inverse you should get an identity matrix. In R, you get an answer that is accurate up to about 16 decimal points? Why can't one get a perfect answer? See for example: c(5,3)->x1 c(3,2)->x2 cbind(x1,x2)->x solve(x)->y x%*%y Vikas Rawal ============================================== This Mail was Scanned for Virus and found Virus free

I want to use grid to modify some boxplots made using ggplot. I would really appreciate if somebody could guide me to a resource on how to use grid to modify such graphics. I guess the basic approach will be similar to using grid to modify lattice graphics. To that extent something that explains use of grid to modify lattice graphics may also be useful. I have gone through vignettes in the grid

For boxplot(), is it possible to pass in a parameter to change the default way that the 1st and 3rd quartiles are computed? (specifically, I'd like to use type 6 described in the quantile function). Also, what are the options for how outliers are computed, and how can one change them? Thank you [[alternative HTML version deleted]]

I have been struggling to get the legends in ggplot2 right or do away with them altogether (on which I have already sent a post). In the following code, the labels argument in the scale_colour_gradient2 does not give me the desired labels in the legend. Could someone explain? qplot(Year,CDR,data=b3,colour=Phase,geom=c("point","line"),legend.position="bottom")->p

I estimated spearman's correlation coefficient using cor(). How do I test for significance? Vikas

This issue has been discussed on this list before but the solutions offerred are not satisfactory. So I thought I shall raise it again. I want to merge two datasets which have three common variables. These variables DO NOT have the same names in both the files. In addition, there are two variables with same name which do not necessarily have exactly same data. That is, there could be some

Hi, Sorry if this is to wrong mailing list. In that case, please point me to correct mailing list. Please also excuse rather long mail - I am not sure what piece of information would be useful for anybody who could help me. Couple of days back I had put a query about box-plots using GUI. I got some excellent suggestions. One of them was to use JGR/Deducer. It worked quite well for my needs.

Hello everyone, I run R on Gentoo Linux and this week I upgraded R from 2.5.0 to 2.6.0. With the new build, I have stumbled upon an unpleasant problem: I can no longer install packages from CRAN through a transparent proxy. With the previous version, I simply added to /usr/lib/R/etc/Renviron the following line and it functioned like a charm: ## Proxy settings http_proxy="SERVER:3128"

This does seem to fix my problem: > Sys.getenv("http_proxy") http_proxy "http://gproxy1.pfizer.com/" > url("http://cran.r-project.org/src/contrib/PACKAGES",'r') description "http://cran.r-project.org/src/contrib/PACKAGES" class

Yum using proxy that requires authentication and a Password that contains the two characters \/ fails normally I can get yum to work with a proxy that requires authentication when required by doing something like http_proxy=http://<my username>:<my password>@<proxy server>:<proxy server port> export http_proxy or by filling in the appropriate information in yum.conf.

Hi All, I have been trying to solve the issue of Xen-based Virtual Machines (as I described earlier); I have the problem of ethernet ports locked to a single Mac address in my lab--hence VM''s can''t communicate using bridging other than their own dom0. To further test/confirm, yesterday I took my laptop at home and connected to my Home-Hub (which issues DHCP based IPs); I

I'm testing a FC5 machine for use in a student lab. R 2.3.1 is installed and seems to work fine. There is one peculiarity - the logins are authenticating to a server, and a "verbose" flag is set somewhere, leading to lots of spurious messages like this request done: ld 0xa227598 msgid 1 which may be confusing R. However, R CMD check seems to fail for packages with no
