Dear R-users, I have very recently started learning about object-oriented programming in R. I am far from being an expert in programming, although I do have an elementary C++ background. Please take a look at these lines of code. > some.data = data.frame(V1 = 1:5, V2 = 6:10) ; > p.plot = ggplot(data=some.data,aes(x=V1, y=V2)) ; > class(p.plot) ; > [1] "ggplot" My

Dear List, I would like to create several graphs of similar data. I have x and y values for several different individuals (in this case fish). I would like to plot the x and y values for each fish separately. I can do it using a for loop, but I think I should be using "apply". Please let me know what I am doing wrong, or if there is a "better" way to do this. What I have

Hi, Is there a way to convert a matrix into a vector representing all permutations of values and column/row headings with native R functions? I did this with 2 nested for loops and it took about 25 minutes to run on a ~700x700 matrix. I'm assuming there must be a smarter way to do this with R's vector commands, but being new to R, I'm having trouble making it work. Thanks,

Hi list, Would someone please give me a hint how to extract the between and within subject StdDev from "lme" fit? Below is the output from the fit, but I couldn't find the number 0.3927714 anywhere in the fitted object. Thanks in advance for your help! Random effects: Formula: ~1 | group (Intercept) Residual StdDev: 0.3927714 0.7857085 Best, Auston

Dear all - We perform some measurements with a machine that needs to be recalibrated. The best calibration we get with polynomial regression. The data might look like follows: > true_y <- c(1:50)*.8 > # the real values > m_y <- c((1:21)*1.1, 21.1, 22.2, 23.3 ,c(25:50)*.9)/0.3-5.2 > # the measured data > x <- c(1:50) > # and the x-axes > > # Now I do the following:

Hi all, I have a binary matrix with NAs included. Each row and column includes at least one NA, so I don't want to omit them. Is there a way to sum across rows and columns, ignoring the NAs but not deleting the row or column? If not, I suppose I can write a loop function, but I have learned that it is best to stay away from loops if possible. Thanks for any help, Wade

Hi all, is there any function to find some words in a character-string? For example suppose the string is : "gdfsa-sdhchc-88", now I want to find whether this string contains "sdhch". Is there any R function to do that? Regards, -- View this message in context: http://www.nabble.com/Searching-within-a-ch.-string-tp23484010p23484010.html Sent from the R help mailing list

Hello all I am looking to learn R and was thumbing through volume 1 of "R reference manual - Base Package". I'm sorry if this is ludicrously silly to ask, but is this book worth the investment as a good way to learn how to use R? AG

We would like to load data from Statistics Canada (http://www.statcan.gc.ca/) using R, for example, Employment and unemployment rates. It seems to me that the tables are displayed in HTML. I was wondering if you know how to load these tables. Thanks, -james

Dear list I have managed to write a short program to evaluate data which is inputted from a csv file using the following x = read.csv("wms_results.csv", header=TRUE) All works fine but since I have a number of similar data files which have different names, I would like the program to allow me to input the file name, rather than having to edit the program. >From the documentation I

Hi I'm fairly new to R and am trying to analyse some large spectral datasets using stepwise regression (fairly standard in this area). I have a field sampled dataset, of which a proportion has been held back for validation. I gather than step() needs to be fed a regression model and lm() can produce a multiple regression. I had thought something like: spectra.lm <-

Hello, I am writing out to a file and have two quick questions that I can't seem to track down the correct answers for. Luckily, I *think* they are both simple enough that someone might be able to point me in the right direction on them without too much trouble. Both questions relate to the process below where CompleteFrame is a data frame containing what I want printed to a file. filename

Hi. I am very new to R and have been diligently working my way through the manual and various tutorials. I am now trying to work with some of my own data and have encountered a problem that I need to fix. I have a dataframe with 8 columns and approximately 850 rows. I have provided an excerpt of the dataframe below. Within column 6 (Question) the numbers 1:33 repeat down the entire column.

There appears to be a bug in RUnit. Given a testsuite testsuite.math, say, when I run: runTestSuite(testsuite.math) this works fine, provided there are no extraneous files in the unit test subdirectory. But if there are any Emacs temp files (with names that end with '~') then runTestSuite gets confused and tries to run functions from the temp files as well. [[alternative HTML version

Hi! I'm new to R programming, though I've been programming in other languages for years. One thing I find most frustrating about R is how difficult it is to use Google (or any other search tool) to look for answers to my R-related questions. With languages with even slightly more distinctive names like Perl, Java, Python, Matlab, OCaml, etc., usually including the name of the language

Hello, I'm trying to make .DollarNames generic and implement a method for it in a package. .DollarNames is the function that is now called to get completion possibilities. My R code looks like this: setGeneric( ".DollarNames" ) setClass("track", representation(x="numeric", y="numeric")) ## A class extending the previous, adding one more

Hello, I want to import R-output via Rserve to Java, especially for the function ctree from the package party. Rserve is working properly. Yet, I only get the predictions with the Java code try{ RConnection c = new RConnection(); ... c.voidEval("modell <- ctree(...)"); REXP y = c.eval("nodes(modell,1)[[1]]$prediction"); ...

Dear R-specialists, I am trying to create a Makefile that will first convert all my .Rnw files into .tex files and then, that will run the LaTeX compiler to produce a pdf document. This issue has been discussed before. Hence, I've basically adapted a Makefile I found at http://n4.nabble.com/R-Sweave-R-and-complex-latex-projects-td810020.html#a810023 to make it compatible with a Windows

Hi I have a string "56 Fe [1]" that I would like to use as a variable name by using "assign" however I think the spaces and brackets might be causing R some trouble. How can I change the string so that it just becomes 56Fe1 and can be used as a variable name. Thank You Kurt _________________________________________________________________ [[elided Hotmail spam]]
