Hi: I have a question about installing R (and modules) on a Unix system (AIX). Can I just gunzip (or the equivalent) the installation files into my home directory or will I need someone with root access to install R? I am hoping that the answer is the former (I can unzip all files to a directory R that I create under my home directory and I can start using it). Could you please help me with this

Dear R-helpers, I wonder if I could impose upon you for forther assistance, this time with dataframes: hopefully this will be of general interest, as I personally have found them hard to get to grips with. I was trying to transpose rows and cols and move col1 to the names. Then all sorts of things go wrong. Although the end result looks the same, page() shows the structure to be quite

Hi all, I work with linux and SUSE 8.1 in a W2K PDC environment. I successfully configured Samba to be able to connect from the Wk2 computers to linux and vice versa with one exception: I'm not able to see the public shares of the window computers from linux (NetShareEnum failed, NT_STATUS_ACCESS_DENIED) unless I provide a username and password. From Windows to Windows it's no problem to

We have "upgraded" from NT Terminal Server to Wk2. In Windows NT we set the registry MulitpleUsersOnConnection = false. What is thier in equivilance for Windows 2000? Our Samba is running out of free connections per Terminal Server. Currently that number is 128. We have 5 terminal servers and each server spawns a single smbd process with 128 connections. Do I have to increase the

Hello all, R2.1.1, Wk2 I am doing some two-step plotting, first using plot() to illustrate the datapoints and then using abline() to place a trend line from a fitted model into the plot. Everything works well as long as the formula of the fitted model i of the type: m1 <- lm(Dependent ~ Independent) then abline(m1) puts the proper straight line into the plot. But if I use: m2 <-

Hello, I have the following task I'd like to accomplish: A file contains 5 columns of data (several hundred rows), let's call them a, b, c, d and e (ie these are their column headers) I also have a set of definitions, e.g., f = a + b g = a * 3 h = c + d etc. I would like to write out a new .rda file that contains columns a b c d e f g h etc. I.e. , the original data plus new columns

Dear ALL, I fear my question has already been answered many times before, but I haven't fund that in archives... I am working on spatial datasets and, in most arrays I'm handling, there are two columns dedicated to (x,y)-coords. For different reasons - notably to draw image() plots, I need to have these two columns sorted in increasing order. But sort() and order() seem to apply to

Hello fellow R people, I can not figure out a pretty way to use strplit with vectors Imagine that I got the following data from someone with ID's representing several factors ID data A1-B1-t1 0 A1-B1-t2 1 A1-B2-t1 5 A1-B2-t2 10 A1-B10-t1 0 A1-B10-t2 1 A1-B20-t1 5 A1-B20-t2 10 ...

Hi. i have a data, and there is 3 columns, Month, Year and Total. and there is over 1000 rows for them because there is 87 years data for every month, so there is month from Jan-Dec, and year from 1900-1987, so i was wondering if i would want to make 12 groups (Jan,Feb.......,Dec), and put each year's total into the corresponding month (so every month group will have 88 values of total) how

Hi Guys, I am trying to create 20 indivudual line graphs that will be updated on a weekly bases. I have managed to read in my data from SQL and defined my loop. I am having difficulty in plotting the data and I think it may have something to do with the way my data has been read in and maybe I need to change it in a dataframe?! Easch graph will be based on PolyNam, so this is defined in the
