similar to: Number of digits in paste funciton

Hello, I am writing this message because of an incorrect output by paste(). Please try the following script to see if the evidence I collected is reproducible: x <- c(10152, 28177); y <- c(9576, 26625); d <- y - x; d; [1] -576 -1552 paste(d, collapse = ", "); [1] "-576, -1552" x <- x / 1000; y <- y / 1000; d <- y - x; d; [1] -0.576 -1.552 paste(d,

Hi! Let us define random variable: > x = seq(0,1,length=100) If we calculate variance following definition E[(x-E(x))^2] we get: > mean( (x - mean(x))^2 ) # == mean(x^2) - mean(x)^2 0.08501684 And if we use internal R function var: > var(x) 0.08587559 Can anyone tells me why the difference?

Dear R team, The following piece of code (to use the lsa package) works fine on my mac os x, but when I run the same code on Windows XP, it doesn't work any more. ### code: library("lsa") matrix1 = textmatrix("C:\\Documents and Settings\\tine stalmans.TINE. 000\\LSA\\cuentos\\", stemming=TRUE, language="spanish", minWordLength=2, minDocFreq=1,

Hi R folks, How can I generate the discriment function from lda? I have an unbalanced data set. one class has about 25 entries and another class has about 200 entries. I used lda for classification > z<- lda(V3 ~ V1+V2, data) > z Prior probabilities of groups: 0 1 0.91111111 0.08888889 Group means: V1 V2 0 0.4445161 0.04723951 1 0.4058900

Hello everybody, I have encountered a problem with the inverse Gaussian distribution. It is very likely that it will not work regardless of the data input. I have programmed this regression and it works fine no matter which distribution the response comes from. If you run this example (first tried and already got the error) set.seed(1234) y = abs( rnorm(150) ) glm( y ~ ., iris, family =

The patch is incorrect because the SmallPtrSetImpl is neither a template nor has an "insert" function... After a detailed look at the header of SmallPtrSet, I found that the

For SSA values, simply iterate over all of the instructions within the

Hi, all; How can I get the number of variables in a function/module (both the number of variables in original source program and the number of temporal variables for ssa-form)? I’m dealing with some dataflow analysis problem and need the information of variables. Appreciate any help. Thanks. Star.Tan -------------- next part -------------- An HTML attachment was scrubbed...

Is there a generic function that gives the machine instructions and their patterns given in the .td files of a backend specification ? or a subset which match a certain opcode ? otherwise how are the machine instructions being accessed/matched for instruction selection ? -Omer -------------- next part -------------- An HTML attachment was scrubbed...

Hi! Does anyone know hot to save (to png, pdf, ...) only plot area. That is without box around, titles, axis, ... I tried: par(mar=c(0,0,0,0)) and it works for internal viewer (linux and windows). But when I save the image in png it adds that annoying margin around plot area. Any ideas? by, Tine

Hi, everyone, I'm new to R and the List, and excited to be here. I am coming from a background working in SPSS 16, primarily, which has a lot of easy options for reading in data. I am working in R in an Ubuntu Linux environment, and I'm learning with R Commander. Now, here's my question. In my line of work, I'm used to getting data in some kind of flat ASCII format with a

Hi! I was just wondering is there anyway to overload operator for custom class. For example: I have two matrices A and B with same dimensions. I want to overload operator '+' with my own function. Or even better can I create my own (new) operator. Example: A+-B where '+-' would be some function. bye, Tine

I'm not aware of any dump utility functions to display that information concisely. I agree such a thing would be

Unfortunately there is currently no great way to do this. Some options are: 1. Pin one operand to a specific register, one that isn't allocated (e.g. R12). Use copyto/fromreg to get to it.

Hi I want to port speex to my pocket PC iPAQ1945 which has a Samsung processor 2410, an ARM9-based processor. I would like to write the specific optimized code for this chip. I had some experience at DSP chip and fixed-point coding but know nothing about embedded system and ARM. Could someone tell me some hint how to write optimized code for this pocket PC. If you can give me some links that will

The ARM has a multiply instruction of the form Rd=Rm*Rs where Rd != Rm. How can I add this requirement to the instruction definition? Thanks, Rafael

Dear all, For analysis of a longitudinal data set with fixed measurement in time I built a gls model (nlme). For testing hypotheses in this model I used the linear.hypothesis function from the car package. A check with the results obtained in SAS proc MIXED with a repeated statement revealed an inconsistency in the results. The problem can be that the linear.hypothesis function (1) only gives the

I stumbled on the fact that text_area_tag does not HTML escape its content by default. For example: text_area_tag "body", "</textarea><script>alert(''xss'');<script>" If you try that, you''ll see that the content is inserted literally. Considering the fact that the tag helpers all encode their attribute values by default, does this

Dear friends. Every loop of my program will result in a list that is very long, with a structure similar to the one below: Lst <- list(name="Fred", wife="Mary", daily.incomes=c(1:850)) Please notice the large size of "daily.incomes". I need to store all such lists in a csv file so that I can easily view them in Excel. Excel cannot display a row of more than 300
