I have used Mike Powell's optimization routine (VA05AD) from the Harwell Subroutine Library (HSL) for more than 20 years. It is no exaggeration to say that it has helped make my career (thanks Mike). I recently learned that I am not alone in this respect - apparently it still has a loyal following in all sorts of fields! It is an exceedingly fine piece of software - fast, reliable and easy to...

Hi all, I have the following x1<-paste("A", 1:6, sep = "") x2<- round(rgamma(6,2,1)) x3<-paste("B", 1:6, sep = "") x4<- round(rgamma(6,2,1)) data1 <- data.frame(x1,x2,x3,x4) I would like to get data2 <- c(A1=4, A2=1, A3=0,...) Is there any standard for such a case? Thank you very much in advance, Diego

...ds, I've lost everything. I know that it's possible to recode this so problems don't occur, but the point is that the answer is unexpected. Can anybody explain if this behaviour is intentional or useful in some way, or is it an oversight? Regards, Richie.

Hi There, There seems to be a way for calling R from .net. However, is there anyway for calling .net/C# code from R? Something similar to the RJava package for .net? Thanks a mil!

Good afternoon everybody, I am sorry, this question might look trivial to some of you, but I read quite a lot of stuff about package creation and I would like a bit of you advices. I would like to develop a core library which I will be using both from R and from C#. I read that it was possible to import DLL to R. The thing is, I am not sure that the DLL created with C# will be compatible. I

Hi all, I'm looking to add a "density" smoother on top of a hist when Freq=T. In order to do this I can use the relation between count and density, but I would like to know if there is a way for me to predict it upfront. Here is an example: set.seed(242) z = rnorm(30) hist_z <- hist(z) hist_z$counts / hist_z$density # the relation is 15 # why is this 15 ?? # So I can now do:

I want to run deconvolution of a time series by an impulse or point-spread function through Wiener filter, regularized filter, Lucy-Richardson method, or any other approaches. I searched the CRAN website and the mailing list archive, but could not find any package for such a deconvolution analysis. Does anybody know an existing R function for deconvolution? TIA, Gang

Hi, the second step in my exercice is to calculate the sum of the amout for each class et not the frequency i have this vector x           y 1          100 2          1500 3          3250 4          6250 5          2000 6           450 i want to use the function table and cat to calculate the sum of the amount in each class [0-1000], [1000-3000],[> 3000] Thank you for your help??

Hello everyone, I get some data in the following format and I would like to combine them to form a dataframe. The data is like: cbcname1 = 0.1, cbcname2= 0.2, cbcname3=0.3,... name1, name2, name2 are just some random names. I would like to achieve sth like: (cbcname1=0.1, cbcname2=0.2, cbcname3=0.3,......) I am using the following codes do.call(cbind,

Hi, I have to match names where names can be recorded with errors or additions. Now I am searching for a string search function which returns always the "closest" match. E.g. searching for "Washington" it should return only Washington but not Washington, D.C. But it also could be that the list contains only "Hamburg" but the record I am searching for is

During the diagnostics of my SAN failure last week we thought we had seen a backplane failure due to high error counts with ''lsiutil''. However, even with a new backplane and ruling out failed cards (MPXIO or singular) or bad cables I''m still seeing my error count with LSIUTIL increment. I''ve got no disks attached to the array right now so I''ve also

Hello, I have a survivor curve that shows account cancellations during the past 3.5 months.  Fortunately for our business, but unfortunately for my analysis, the survivor curve doesn't yet pass through 50%.  Is there a safe way to extend the survivor curve and estimate at what time we'll hit 50%? We started a new program 3.5 months ago, and I believe that this set of accounts behaves
