Hi, Can someone please give me a pointer as to how I can set values of an array? Why does the code below not work? my_array <- array(dim=c(2,2)) my_array[][] = 0 my_array [,1] [,2] [1,] 0 0 [2,] 0 0 for(i in seq(1,2,by=1)){ for(j in seq(1,2,by=1)){ my_array[i][j] = 5 } } Warning messages: 1: In my_array[i][j] = 5 : number of items to replace is not a multiple of

Dear R-users, suppose I have three dataframes like these df1: mydate min_temp 31032013 12 01042013 8 02042013 -999 df2: mydate min_temp 31032013 10 01042013 11 02042013 14 df3: mydate min_temp 31032013 4 01042013 3 02042013 5 where -999 means that the temperature data is not available (at the moment I cannot change it to NA because I am not the db administrator); suppose also that oggi is

Hello, I am looking for a way to transform an array into a list (or a string). My array has two columns 1 and 2, and I would like to create a list of the values. Let's say I have : x1 x2 1 a b 2 c d 3 e f 4 g h What I would like to obtain is a,b,c,d,e,f,g,h. I tried without success melt and reshape ( reshape(my_array,

Hello I've been looking at a debuginfo issue on an out-of-tree target which uses DWARF aranges. The problem is that aranges are generated for both data and code objects, and the debugger gets confused when program addresses overlap data addresses. The target is a Harvard Architecture CPU, so the appearance of overlapping address ranges is not in itself a bug as they reside in different

I am going nuts here.. I have a form where users can write a city name (used with auto_complete) - and once they click on the desired city in the dropdown menu - I would like to have the Country field filled automatically as well... Is this possible at all ? If so, can somebody please tell me where I can find some documentation on the subject, or preferrably an example ? Many thanks in

Hi everyone, I am trying to simulate the ''grep -v'' behavior in an array: Ex: vgrep([''aaa'',''bbb'',''ccc'',''aaaddd''], ''aaa'') Would return: [''bbb'', ''ccc''] So I tried to use ruby to do it: normally the ''-'' operation should be

CentOS 7 box. As there's no package in any of the repos, we're trying to install scikit-learn in the user's space. It refuses. My late try was, after d/l a .whl from last year, hoping that would work with the numpy package in the regular repos, I did a pip install --user scikit-learn..., and it still seems to want to write to system space: OSError: [Errno 13] Permission denied:

Just had a look at scikit-learn. An issue you have with the current version of this package is that is depends on NumPy (>= 1.8.2). The version of NumPy in CentOS 7 base is 1.7.1. You may need to look at building a Python virtual environment. You can google that ;) On Tue, Apr 10, 2018 at 9:43 AM, Richard Grainger <grainger at gmail.com> wrote: > I created the epypel (Extra Extra

Per the recent (seeming) consensus regarding incubating new projects under the LLVM organization, I would like to trial the process by requesting to incubate mlir-npcomp <https://github.com/google/mlir-npcomp>. The project is still quite young and has been primarily developed part time by myself and Sean Silva over the last ~2 months. We set it up following discussion of a Numpy/Scipy op set

Hi, I am using reticulate and a virtual environment (not conda) to run Python scripts from RStudio. However, when I try to use my own (existing) virtual environment, reticulate does not use it. If I run my scripts, the installed modules (e.g., py_install("pandas", "mmstat4.hu.data")) are not found. I believe this happens because reticulate is using r-reticulate instead of

Have you tried https://rstudio.github.io/reticulate/ ? Generally speaking, complex nonstandard package specific questions such as yours rarely get a reply here -- there are 20,000+ packages (and counting) after all! As reticulate was created by and integrated with RStudio/Posit, I would think their site and help resources might be a better venue. Of course, if you don't use RStudio, you may

No, seriously: I've had more than one person at work wonder what math toolset could be loaded onto iOS. So, before Matlab, FreeMat, Mathematia, SciLab, Octave, or numpy (:-) ) produces a version for iPad, any chance someone is working on R for iPad?

Hi guys, bought the ROR book. I understand most of it and really like it. There is just on thing I just dont get. Lets take this code for example. def list @products = paginate :product, :per_page => 10 end As far as I understand @products should be some kinda hash or array, with the data of the Database inside. How can I display this array ? One solution is to do it like this (like in

Hi, what is the best way to go about mixing effects when joining two videos, like crossfading? Once I have the individual images as numpy arrays, the mixing itself is the easy part (I'll just use numpy + scipy for that, or any other python lib). However, it's not clear to me how (and especially when) to handle decoding and encoding properly. So lets say I create a video tutorial

Hi all, I try to utilize RSPython to invoke Python from R. For me it works pretty fine for basic applications, but I have 3 problems that may be related. (1) I can't load other packages but "standard" ones also when I adjust the PythonPath: > importPythonModule('sys', all=T) NULL > importPythonModule('numpy', all=T) Error in
