similar to: Speed Optimization: Faster Way of Accessing data.frame in a Loop?

Dear r-helpers! I am kind of new to R. I would like to calculate the mean of the numbers of this expression: data(USArrests) USArrests[row.names(M) == "Alabama",] class() tells me it's a ``data.frame,'' what I actually desire is to get all numbers of a row as a vector or a list to let mean() calculate the mean of the whole row. (I know this doesn't make sense

Dear list! I am interested in learning about MLE and I wonder whether it is possible to use the examples for maximum likelihood estimation given in 8.7 in MASSv3 with R? AFAIU R does not have a direct replacement for S-PLUS's ms() which the examples use for the fitting, but optim() may be of help for me. However, I am not sure how I can convert the use of ms() using optim()--is there an

Hi, below is the output of the kernel just before it goes down and crashes. I have to use "xm destroy" to kill it. I have tried the enable/disable the "Optimize for Size" setting in the kernel. I hopes that it''s some kind of compiler bug because of the "invalid opcode" thing. But actually I don''t a clue what this might be caused by. Do you

Hello! I have two vectors and want to know how many of their elements are equal - what's the best way to do this in R? Best regards, Sven

Andrew, Thanks very much. After sending my question, I discovered that the DCOM area was disabled in the build as of 8 years ago, so it became clear that this is not currently supported in any way.

Hello, I apologize for posting prototype related email to this list, yet I have not seen any reference to email or list on the prototype web site and I know the author of that library is part of the rails development team so I am trying to reach him. Basically I have installed "FireBug" which is a javascript/html/css/dom debugger for firefox and since I plugged prototype.js and

I see that the Samba sources include the WMI client (wmic), but I have not succeeded in getting the configure/make to build it. Does anyone know if this feature is supported in current (4.7.4) Samba, and, if so, how to build it? Steve Koehler

Hello, I just found this message in our dovecot logfiles: "Disconnected: BUG: Unknown internal error" Should I worry about this ? There are no complaints yet (although it is not limited to one user). It seems to occur with different clients (Apple/MacOS mail, Windows/Thunderbird, Pine). We're running dovecot 1.0.10 on Solaris 10 with mboxes (NFS) and local index storage. There are

Hallo, I have a question concerning SVM regression in R. I intend to use SVMs for feature selection (and knowledge discovery). For this purpose I will need to extract the weights that are associated with my features. I understand from a previous thread on SVM classification, that predictive models can be derived from SVs, coefficiants and rhos, but it is unclear for me how to transfer this

Hi, is there advice how to subset a data.frame, where until R version 1.7.0 it was possible to write > data[["subset"]] which meant the same as > data$subset (data is a data.frame). From 1.7.1 on this does not seem to work longer. Could there be a bug in downwards compatibility? sincerely yours Dirk

Hi there, I have a data frame DF with 40 millions strings and their frequency. I am searching for strings with a given pattern and I am trying to speed up this part of my code. I try many options but so far I am not satisfied. I tried: - grepl and subset are equivalent in term of processing time grepl(paste0("^",pattern),df$Strings) subset(df,
