similar to: Saving a plot in R-LINUX

Hi, Today I came upon unexpected R behaviour. I did some modelling and the result was R object, about 28MB size (nested list, with matrixes as list elements). When I was saving the session with save.image, the resulting .RData file was 300MB. There were no other large objects: >

Dear all, There have been one or two questions posted to the list regarding the optim error "non-finite finite-difference value [4]." The error apparently means that the 4th element of the gradient is non-finite. My question is what part(s) of my program should I fiddle with in an attempt to fix it? Starting values? Something in the log-likelihood itself? Perhaps the data

I wrote the mail to R-devel, but nobody answered it. I use Gnome on my computer and sometimes I use its default text editor gedit. It uses gtksourceview library for syntax highlighting. I decided that it would be nice if gedit supported R

Hi, I was trying to repeat the estimation of threshold GARCH models from the book "Analysis of Financial Time Series" by Ruey S. Tsay, and I was succesfull, but I had to use "for" loop, which is quite slow. The loop is necessary, since you need to calculate recursive sequence. Is there a faster way to do this in R, without using loops? The model is such: r_t = \mu + \alpha_2

Good day everyone. I have a large dataset of 1 min wind speeds covering 5 years. How can I make an array of maximum daily values? The vectors I have are: 'VDATE' with dates in format '%Y-%m-%d' (like '1992-10-28') and 'WS' with wind speed data (same number of elements as VDATE). I want an array with 2 columns: Max daily wind speed and corresponding day. Has

Hi, Dirk Eddelbuettel advised me to write here. Here is my original letter to him: I would like to enquire about package r-cran-rjava on Debian jesse. It seems that if default-jre package is not installed, but openjdk-7-jre is installed, then library(rJava) in R fails. I?ve been bitten by this today and I wonder whether this an issue of mine, or is this a possible bug. My server admin used

Hi, Sweave for some reason does not respect encoding setting in pdf.options. Everything is OK with ps.options. Thus when using non-default encoding for graphs, resulting graphics eps file is correct, but pdf file is not. Workaround is very simple, just use latex->dvips->ps2pdf chain to get the intended pdf document. I tried to find the explanation for this, but I did not find anything. If

Good day everyone, I want to use zoo(aggregate) to calculate 15-min mean values from a wind dataset which has 1-min values. The data I have looks like this: vector VDATE vector WS 1 1998-10-22:02:11 12.5 2 1998-10-22:02:12 10.1 3 1998-10-22:02:13 11.2 4 1998-10-22:02:14 10.5 5 1998-10-22:02:15 11.5 . . . n

Good day everyone, Can anyone suggest an effective method to solve the following problem: I have 2 dataframes D1 and D2 as follows: D1: dates ws wc pwc 2005-10-19:12:00 10.8 80 81 2005-10-20:12:00 12.3 5 15 2005-10-21:15:00 12.3 3 15 2005-10-22:15:00 11.3 13 95 2005-10-23:12:00 12.3 13 2 2005-10-24:15:00 10.3 2 95 2005-10-25:15:00 10.3 2 2 D2:

Hi, I'm having problems while working with large data sets with R 1.5.1 in windows 2000. Given a integer matrix size of 30 columns and 15000 rows my function should return a boolean matrix size of about 5000 rows and 15000 columns. First of all I tried to run this function on computer with 256 MB of RAM. I increased memory limit of R with memory.limit() up to 512 MB. I was inspecting

Good day everyone, I want to assess the error when fitting a Gram-Charlier CDF to some data 'ws', that is, I want to calculate: Err = |ecdf(ws) - GCh_ser(ws)| The problem is, I cannot get the F(x) values from the ecdf. 'Summary(ecdf())' returns some of the x-axis values, but how do you get the F(x) values? Thank you for any help you can provide. Regards, Augusto

Hi, Is it possible to make R start not from terminal with option --gui=GNOME? Now if in the launcher preferences checkbox run from terminal is not checked, R with option --gui=GNOME doesn't start. If started with checked checkbox, i.e. from terminal, besides R, terminal window also appears, but it is of no use. Yet if it is closed, the R window closes together. Is this a feature, or is

Good day everyone, I am new in R programming (my question may sound trivial to you): is there any way to ask the user to enter a string within an R process, say a filename, make R to recognise it and open the given file? It is a simple exercise in other languages. I am using R2.1.1 in a LINUX machine. Thanks for your help. Augusto -------------------------------------------- Augusto

Good day everyone, I want to use the Gram-Charlier series expansion to model some data. To do that, I need functions to: 1) Calculate 'n' moments from given data 2) Transform 'n' moments to 'n' central moments, or 3) Transform 'n' moments to 'n' cumulants 4) Calculate a number of Hermite polynomials Are there R-functions to do any of the above?

Hello, we have a set of biological cell-size data, which are only available as frequencies of discrete size classes, because of the high effort of manual microscopic measurements. The lengths are approximately gamma distributed, however the shape of the distribution is relatively variable between different samples (maybe it's a mixture in reality). Is there any ML fitting (or

Subject: Error: cannot allocate vector of size 554 Kb X-Mailer: VM 7.00 under 21.4 (patch 6) "Common Lisp" XEmacs Lucid Reply-To: fjmolina at lbl.gov FCC: ~/mail/sent Does anyone know how I can avoid this error?

Dear R-lister Could anyone know how to make a multi-line title for a plot with expression()? In my plot, the title should be writeen in two lines (because it is two long for one line) and it should use a mathematical expression. I tried to use "\n", but "\n" is ignored in expression() call: hist(diffChangeRequestHintsBeforeAnswering[,4], br = 50, xlab = "Skill Change in

Dear list, I have a simple question. If I need to run linear regression on a subset of the dataset, will the following two commands give the same output: lm(y ~ as.factor(x1) + as.factor(x2), data, subset = z==Z[1]) and lm(y ~ as.factor(x1) + as.factor(x2), data[data$z==Z[1],] ) I have got different results running the two commands. Am I missing something here, or it there a bug on the

Does anyone know of a resource for learning the basics of how to manage and manipulate dates and times in R? I have been reading "Introductory Statistics with R" by Peter Dalgaard which is fantastic. But alas, I could find no reference to date and time. I have looked at the reference manual but it is particularly unapproachable. So rather than dense technical talk I would rather see a
