I'm doing a study where people place a deck of cards in a certain order. It's sufficient to assume that their colors & each has a number (it's actually about attributes of hobbies). I'd like to look for patterns in how they've arranged the deck. For each subject I have a list like 3,5,2,4,1, indicating that (s)he chose 3 first, then 5, then 2. . . . I think what I first

I've got a data set with integer codes from 0--3. I'd like a histogram with a single bar for 0, 1, 2 and 3. I'd like each of the 4 bars centered over a label. hist(mydata, breaks=4, main="Simulation") gives me three bars. The best I've been able to do is do something like print(hist((wexp), breaks=25, main="Simulation")) This gives me something

I've got a graph with really long labels. I've tried decreasing the font size, but they're still getting truncated. I've RTFMed & it seems that mgp should have something to do with this, but I can't make it work. I need about 2-3x as much space for labels as is available by default (or on the example below). boxplot(split(ranks,c(1:25)), names=items, horizontal=F)

I've got a background in computer science & have been using Linux for nearly a decade. I'm working on a Ph.D. in education and technology and I essentially live in emacs and do all of my writing in LaTeX. To me R seems like the perfect stats package. Unfortunately, the learning curve is killing me. I feel like that if I'd waded through pulling down menus in SPSS or SAS I could

Another naive stats question. I'm trying to better understand what boxplots are telling me. I think what I see is the median and the boundaries of the 1st and 3rd quartiles. The whiskers represent the range of the data unless there are points which are outside "range" (default: 1.5) times the distance from the median to that quartile. Is that right? I've read the

I'm an R novice and my colleagues are about to convince me to get my data into SPSS, which will presumably be easier for someone who doesn't live in R to point and click his way into some kind of analysis that might be meaningful. I've got two groups of subjects (classkey in the table below). They've each received several different treatments. One measure is a 1-7 rating taken

I'm running R (latest) on linux, using gnome. I was wondering how export the plots to an image file of sort sort. I can't find anything obvious in the documentation. Thanks in advace.

I've got a table of 1 row per observation. 16 questions * n subjects * 4 classrooms (2 teachers * 2 conditions) I'd like to run some simple regressions that look something like this: lm(length ~ elapsed) I'd like to do the regressions several times, split out by questionkey, student, class. What I've been doing is using a series of which's to create new data sets (e.g.

Thanks for all the help on my previous histogram problem. I intend to summarize the solutions back to the list Real Soon Now, but first, I've got another problem. I've made a bar chart that reports means. I'd like to put the number of observations on top of each bar. Here's what I've got: barplot((subset$x), col=grey(.5), ylab="Mean Engagement

Hi, I have struggled to re-implement the RMySQL package after upgrading from SuSe 6.3 to 7.2 and from R 1.2.1 to R 1.3.1, to no avail It compiles happily but when loading the package I get the following error > library(RMySQL) Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "/home/jniesch/R_HOME/lib/R/library/RMySQL/libs/RMySQL.so":

Hello list, Out of interest, I've been trying to compile R on WinXP with MinGW/MSYS. I've been following the instructions for compiling R on windows as closely as possible. Below is my configure statement, which seems to work okay except that no browser or pdf viewer is found, and html docs will not be compiled... I've tried enabling/disabling many different options, and I also add

So I have this nice, simple web server up running. Its purpose is to allow me external testing with HIP, and to provide some files for external distribution. Of course, there it is sitting on port 80 and the attacks are coming in per logwatch report. Examples from the report include: Requests with error response codes 404 Not Found //phpMyAdmin-2.5.1/scripts/setup.php: 1

I have just installed R on a Windows NT system. Unfortunately I am unable to open any of the data files I wish to work with. I have tried using read.table and scan and to the best of my knowledge am using the correct syntax. The error message I receive is Error in file(file, "r") : cannot open file [file name] I have the data in text files in white-space delimited form. I put them

Hi all, I have experimented a segmentation fault error using RMySQL_0.4-6 library in R 1.5.1.

Can anyone tell me what's wrong with this command?? xx<-subset(x,LOCAL.NAME==c("Chifumbata","Chikota"),select=c(13,16,19,23,26,2 9,30,33:48)) Warning message: longer object length is not a multiple of shorter object length in: LOCAL.NAME == c("Chifumbata", "Chikota") both of the following commands work fine

Dear Users, I use Sgeostat to calculate co variogram (function est.variogram with two variables). If i inverse the 2 variables in the functions, the co variogram change! Normaly it is symmetric, isn't it? Someone could me explain why, or give me an idea to calculate co variogram in a easy way... Thanks in advance Laurent ps : sorry for my english Laurent William Dubroca Centre de

I am just learning to use R. The data from my current project are integer-valued. I am able to create scatterplots, but I would like to have some indication on the plots when multiple data points overlap at the same x-y coordinate. SPSS uses 'petals', and other packages use jitter. Are there similar options in R? I have not been able to find any in the documentation. Thanks very much,

Hello Cracks, we want to import 10 x 365 files containing each 7 variables with 1211 rows. The filenames end with numbers from 1 to 365. We tried a for loop to import using read.table but we couldn't create the r objects within the loop. We want each file in an own r-objekt (matrix). Does anyone know what can be done? Thanks, Felix -- Felix Tiefenbacher Eidg. Institut f?r Schnee- und

Is it true that append=T does not work in assignTable() in RMySQL ? More specifically: I cannot append a data.frame to an existing table in a MySQL database, although I can use the same data.frame to create a new table. Even more specifically: > assignTable(con,"employee",dita,append=T) Error in execStatement.MySQLConnection(con, statement, ...) : RS-DBI driver: (could not
