I have a dataset which I want to model using a Poisson distribution, with a given parameter. I would like to know what is the proper way to do a ''goodness of fit'' test using R. I know the steps I''d take if I were to do it ''manually'': grouping the numbers into classes, calculating the expected frequencies using ''ppois'', then

Has anyone got vim to have syntax highlighting with R function codes? I know there's something similar that works with emacs (ESS or something like that), but I was wondering if anyone knew an equivalent that worked with vim.

Is it possible to use R as a data-mining tool? Here's the problem I've got. I have a couple of data sets consisting of results from a cDNA microarray experiment - the details about the biology don't really matter here, the same theory applies for any other data-mining task (that's why I thought it'd be more appropriate to post this on r-user). Each of these datasets consists

Hi, my doubt is very simple. I'm sure I've seen someone using something like this before, but unfortunatelly my searches in the archives were useless. Well, I have some objects called after a name that has a number attached to it, varying. Let's say I have: > ls poly1 poly2 poly3 poly4 poly5 poly6 ... I would like to access these objects using a for(), in which I could do

Is it possible in R to subset a dataframe by more than one factor, all at once? For instance, I have the dataframe: >data p1 p2 p3 p4 p5 p6 p7 p8 p9 p10 pred 1 0 1 0 0 0 0 0 0 0 0 0.5862069 4 0 0 0 0 0 0 0 0 0 1 0.5862069 5 0 0 0 0 0 0 1 0 0 0 0.5862069 6 0 0 0 0 0 0 0 1 0 0 0.5862069 7 0 0 1 0 0 0 0 0 0

I know this is likely very simple. I want to change a matrix that was given to me not sorted by timestamp to sorted by timestamp. It was sorted by CRAH_Name. There are 264k records initially. The CRAH names start at 11 and go to 98 but there are a number of missing values (CRAH_Name), total approx. 50. A small example of the given matrix Time_Stamp Power CRAH_Name 4/16/2012 00:00 3.4862 11

Hello, in the data.frame "resultsfuzzy" I would like to replace the characters in the second column ("5a", "5b", ... "5e") with numbers from 1 to 5. The data.frame has 39150 entries. I seems to work on samples that are << nrow(resultsfuzzy) but it takes suspicously long. Do you have any suggestions how to make the character replacing more

Dear All, I was wondering if it is possible to generate a regression summary (it does not matter at this stage if from an lm or for example a glm estimate) in which to obtain the joint significance of a set of regressors? Examples could be looking at the joint significance level of a polynomial, or of a set of exogenous variables of which is of interest the linear combination suggested by the

Hello all, I have two questions about anova (one is probably VERY basic...) 1 - when one asks for a summary of a trend surface created with surf.ls, he/she gets: > summary(g3r) Analysis of Variance Table Model: surf.ls(np = 3, x = gradiente$east, y = gradiente$north, z = gradiente$num1) Sum Sq Df Mean Sq F value Pr(>F) Regression 215.7182 9 23.968693976

Hi list Maybe someone can help with the following problem (thanks in advance): I need to analisy a long list of data time \fluoscence I want to make one plot with standard deviation and the average data... Could you suggest me how to make that.. The data have this distribution: How can read and extrapolate this data? pippo.csv ps <- read.table(pippo.csv) time fluorescence 0; 0 4.013; 62.96

Dear all, this is probably more a statistics question than an R question but probably there is somebody who can help me nevertheless. I'm running a regression with four predictors (a, b, c, d) and all their interaction effects using lm. Based on theory I assume that a influences y positively. In my output (see below) I see, however, a negative regression coefficient for a. But several of the

I am also having problems receiving my first fax. I get a 320byte file (for a 4 page fax). If I look a the tiff generated, is just has some few dots. I am sending the fax from a notebook with Windows XP to an X100P and using libtiff v3.5.7. Has anyone successfully received faxes ? Output to the console as follows: Changed from phase 0 to 1 > Start receiving document > Changed from

Hi All, I have a vector of data, a vector of bin breakpoints and I want to put my data in the bins and then extract fanciful informations like the mean value of each bin. I know I can write my own function, but I would have thought that R should have somewhere a function that took as arguments something like (data, breaks, what to do with the data in the bins). I surey could not find it

Dear R-helpers, I'm stuck with a little problem that surely has an easy solution but I can't think of a way to solve it. I'd really appreciate any help you can offer me! I'll provide a small example. Given a dataframe data.txt that looks like this: ID freq Var Var_mean Ratio_mean Var_median Ratio_median Var_sum Ratio_min Var_max Ratio_max Var_min

While I was testing this new series (v2) I discovered an huge use of memory and a memory leak in the virtio-vsock driver in the guest when I sent 1-byte packets to the guest. These issues are present since the introduction of the virtio-vsock driver. I added the patches 1 and 2 to fix them in this series in order to better track the performance trends. v1:

I have a problem of using call file to make an auto dial out call through FXO channel. I defined the channel in the call file as "Channel: DAHDI/1/8775203463" When I put the call file under the /var/spool/asterisk/outgoing dir it did not call out but came to the context I defined in extensions.conf as if the callee had answered the call.

Hi all. I'm being asked to connect two networks, each having it's own PDC and it's own LDAP backend. I would like to know if it's possible to make both PDC's serve each a different domain with a single LDAP backend and having users from DOMAIN1 roaming to DOMAIN2 and viceversa. If it's of any use I have, in the past, set up a PDC+BDC configuration having
