Hi All, I am making a serious effort to try to learn R, but one hurdle I am facing is that I need to "see" the data as I walk through the examples in the packages. For instance, many examples on the web start by a command like data("wines"). How can I actually view what the dataset looks like prior to transformations and analysis? I have tried to use edit() , print, and

Dear All, I installed R 2.7.0 and tried to call a dataset i had ealier own called on R2.6.2 but i keep on getting an error: use("maltreat.dta") Error in fromchar(x) : character string is not in a standard unambiguous format Tried doing the same with R2.7.1 but i get the same error.

Dear R-help team, I am getting addicted to using R but keep on getting many challenges on the way especially on data management (data cleaning). I have been wanting to drop all the rows if there values are `NA' or have specific values like 1 or 2 or 3. mdat <- matrix(1:21, nrow = 7, ncol=3, byrow=TRUE, dimnames = list(c("row1",

Dear Sir, I am almost giving up on getting the R-2.9.1 on the ubuntu 9.04 using the instructions found on the R site. I decided to use the R-2.9.1.tar.gz and untarred it. I then typed ./configure and the results are shown below. However, on typing make, I got an error, "No targets specified and no makefile found stop" What is the solution? lmramba at LMramba-dll-d:~$ su Password:

Hi, I am trying to convert a variable a = sample(1:3,100,rep = T) represents choices into a 3X100 dummy varible b with corresponding element set to 1 otherwise 0. eg. a: 1 3 2 1 2 3 1 1.... b: 1 0 0 1 0 0 1 1.. 0 0 1 0 1 0 0 0... 0 1 0 0 0 1 0 0... Is there something like b[a] =1 existing? I could not figure this out myself. ---------------------------------

Don't know if anyone's got experiences on this they'd be able to share... I'm trying to obtain numbers for Kenya/Nigeria, but I'm struggling to find a company selling them. There's one for Nigeria listed on didx.com, but $22/month seems a little steep. Has anyone had any luck getting DIDs for countries in Africa, and are there any companies out there selling them? Thanks

Is there a way of removing all rows with missing values from a data frame? I usually use subset(x, var1!="NA") and repeat for each variable. It would be nice to be able to do it in one fell swoop. Also, surprisingly, it doesn't always work. Sometimes I'm left with an empty set even though not all rows have missing values for the variable. Cheers, mikkel Mikkel Grum,

I have two factors l1, l2, and I'd like to merge them. (Remark: The factors can not be converted to charaters) Function c() does not give me the result I want: > l1 = factor(c('aaaa', 'bbbb')) > l2 = factor(c('ccc', 'dd')) > lMerge = factor(c(l1, l2)) > lMerge [1] 1 2 1 2 Levels: 1 2 > I'd like to merge l1 and l2 and to get lMerge

Hello everyone, I have a problem with smbmount. After I mount a certain share, I can not view files with weird charaters in their name. This happends for example with the copyright char. After searching with Google I still didn't find an answer. I guess it has something to do with a 'charset' command, but I can't figure out wich one, and what character table I should use...

Hi, I was testing Samba 3.0.1 as a logon server on a Solaris 9 Sparc box.

I am a very amateur Rubyist who, amongst other things, likes to use a simple Rails app to query my company''s MySQL config database. The server I now use to do this has got 1.9.1 and Rails 2.3.3. I''ve now hit the ''problems'' related to 1.9 and string encoding, which means that when Rails try to display, say, E acute characters, it throws an invalid byte

I have two problems where I've come up with some code that will do the analysis that I want, but it looks pretty clumsy. In the first case, I calculate the variance on five different columns for each of 14 clusters and get them into one matrix. I get the job done, but I would have thought that it could be done in one or two lines, not six, and be generalized so that it didn't matter how

Salut, Je souhaiterai définir dans mon fichier environement.rb une variable qui puisse être récupéré dans mes controlleurs. Plus précisément je souahiterai initialiser une varible avec l''ip du serveur qui héberge l''appli et pouvoir la récupérer dans mes controlleurs. Je suis sur que c''est trés simple mais je n''ai pas trouvé l''info. Merci ! --
