similar to: Convention difference in tseries.maxdrawdown (PR#8872)

I have a monthly price index series x, the related return series y = diff(log(x)) and a POSIXlt date-time variable dp. I would like to apply annual blocks to compute for example annual block maxima and mean of y. When studying the POSIX classes, in the first stage of the learning curve, I computed the maximum drawdown of x: > mdd <- maxdrawdown(x) > max.dd <- mdd$maxdrawdown > from

Hi, Complete newbie to R here. Just getting started reading manuals and playing with data. I've managed to successfully get my *.csv files into R, however I have to use header=FALSE because the real header starts in line #2. The file format looks like: PORTFOLIO EQUITY TABLE TRADE,MARK-SYS,DATE/TIME,PL/SIZE,PS METHOD,POS SIZE,POS PL,DRAWDOWN,DRAWDOWN(%),EQUITY 1,1,1/8/2004 12:57:00

Hi all, Newbie alert. OK, I'm reading the help file using Ted's suggestion of ?read.csv or ?read.table, etc., and trying to understand exactly what R has created for me when I do the read.csv command. The overall header says read.table creates a 'data.frame', which is fine with me as it works, but throughout the help file I run into the words table, matrix, array and others. Are

I have hundreds of megabytes of price data time series, and perl scripts that extract it to tab delimited files (I have C++ programs that must analyse this data too, so I get Perl to extract it rather than have multiple connections to the DB). I can read the data into an R object without any problems. thedata = read.csv("K:\\Work\\SignalTest\\BP.csv", sep = "\t", header =

Dear folks, I have been struggling to create what I fondly imagined would be a straightforward adaptation of the package's example to my own dataset, which looks at incidence of depression following the birth of initial and up to 3 subsequent children (4 children in all, with all subjects having a first child). I've regarded these as equivalent to tooth eruption and subsequent caries in

R programming question, not machine learning, although that's the content. Apologies to all for whom the following code is eye-burning. I am using foreach() to run a simulation on a randomForest model (actually conditional randomForest ... "party" package). The simulation is in two dimensions. examining how "mtry" and "ntrees" are related in terms of predictive

Hi! I am new to looping and R in general; and I have sent waaaay to much time on this one problem and am about a hair away from doing it manually for the next two days. So, there is a package that while calculating the statistic creates lists (that look like matrices) in the background. Each item (there are 10 items) has one of these ‘matrix looking list’ that I need to extract data from. The

Thanks! Three of the libraries are not found: LLVMX86Disassembler.lib LLVMMCParser.lib LLVMInstCombine.lib ... the third one of those sounds like it might be important, what does it do exactly? But specifying the rest of them with /MD completes the build with this message Creating library toy.lib and object toy.exp LINK : warning LNK4098: defaultlib 'MSVCRTD' conflicts with use of

Has anyone built Compiler-RT on Windows? I am attempting to compile it for ARM, but I get errors from CMake. It appears to be trying to pass VC++ flags to Clang. I am using a version of Clang built from trunk. PS D:\llvm\arm_test\compiler-rt-build> cmake -G Ninja -DCMAKE_C_COMPILER=clang.exe -DCMAKE_CXX_COMPILER=clang++.exe -DCM AKE_RC_COMPILER=rc.exe -DCMAKE_CXX_FLAGS=""

I just pushed a new wxruby-swig, which includes the known MSWin rakefile changes. It also has some significant internal improvements that will make it easier to add classes, and it includes support for one new class (wxEvent). wxruby-swig is now licensed under the "MIT license". wxRuby will remain under the wxWindows license as long as we are releasing the old code base. When we

A transformation pass. If the program works without it, I don't think it is important unless you care about optimization. It is

Has anybody tried the new wxruby-swig from the msvc++ command line compiler using ''rake''? The rakefile seems to depend on the wx_config method, which doesn''t exist for msw because it doesn''t have BASH to execute the shell script. Has anyone hacked the rakefile to fix this? Nick

Hello all! Please forgive me if this is the wrong mailing list for my question. First off, I am on Windows and using git bash for everything: $ uname MINGW32_NT-6.2 I am attempting to essentially do the kalidescope example.
