search for: binarized

I have a dataframe that has a header like so: class value1 value2 value3 class is a factor the actual values in the columns value1, value2 and value3 are 0-255, I wish to binarize these using biclust. I can do this like so: binarize(dataframe[,-1]) this will return a dataframe, but then I lose my first column class, so I thought I could combine it like so: dataframe <-

I have a dataframe in which I have values 0-255, I wish to transpose them such that: if value > 127.5 value = 1 if value < 127.5 value = -1 I did something similar using the "binarize" function of the biclust package, this transforms my dataframe to 0 and 1 values, but I wish to use -1 and 1 and looking for a way in R to do this.

Dear list, I think I'm being dense, but I can't get combn or expand.grid to give me this result. I need to generate a matrix of all 16 possible sequences of 4 boolean elements, 0000 0001 0010 0011 0100 ..... 1111 (in the end I'll have to assign NA to the 0s and some value to the 1s but let's keep it simple) OK, I could go the following route, but I feel like reinventing the

...in the dataset, I used the following three variables to produce crosstabulations (variable names: FOLSTAT, GENDER, ASBIN; all three were categorical variables, FOLSTAT denoted follow up status for the subjects and had seven levels, GENDER denoted sex (two levels: male,female), and ASBIN denoted binarized arsenic concentrations (two levels: "<0.05", ">0.05" denoting less than 0.05 mg/L and more than 0.05 mg/L respectively). To illustrate, I used the following code for crosstabulation: x <- table(FOLSTAT,GENDER,ASBIN) # from the results, I then wanted to subset a t...

Hello people! I'm having trouble while try to run our app in wine.

Hi, Currently I have a dataset of 2400*408. And I would like to apply PCR method to study the any correlation between the tests. My current data is in data.frame and I have formed horizontal(1-407) to be the exact data, and (408) to be my results data(Yes and No) I have also binarized these Yes and No to 1 and -1s. However, when I refer to PCR manual on R, the example of yarn.pcr <- pcr(density ~ NIR, 6, data = yarn, validation = "CV"), I am not sure how can I adapt the command based line to my sample dataset. It seems that they label each horizontal (columns) as...

Hi, I would like to figure out the meaning of the return value of these two functions. Here are the default definitions I find from R source code: static int altreal_Is_sorted_default(SEXP x) { return UNKNOWN_SORTEDNESS; } static int altreal_No_NA_default(SEXP x) { return 0; } I guess the macro *UNKNOWN_SORTEDNESS *in *Is_sorted* and 0 in *No_NA *simply means unknown sorted/NA status of

Sorry I didn't answer before. Martin, thanks very much for your notes and for tidying the function up! About matPower, I didn't realise that where it says "pot <- pot %*% p ot", consumption of memory was higer than it was on the original algorithm, And about the other function in this thread, matExp, I can remember I us look to m >Message: 27

Hello, Definitely not any (constructive) comments on the NHW Image codec? According to my tests, it can compare good with reference codecs like x264 intra and WebP. Yes, the codec is still experimental and is optimized for visual (subjective) evaluation, not PSNR.Its main feature is again that it would have a little more neatness/sharpness and a little less precision (residual coding is applied

...ave any information about whether there are NAs, it says "no" (returning 0, ie FALSE). Also please note, it is possible there may be another API point in the future which asks the object *how many NAs it has.??* If that materializes, No_NA would just consume the answer to thatto get the binarized version, but again there is nothing like that in there now. Hope that helps. Best, ~G On Wed, Sep 11, 2019 at 12:04 AM Wang Jiefei <szwjf08 at gmail.com> wrote: > Hi, > > > > I would like to figure out the meaning of the return value of these two > functions.

Dear developers, I am a maintainer of the CORElearn package which uses OpenMP multithreading to speed up some computations. When producing a new release we tested the package with the latest R 2.12.0. On Linux the package works normally. On Windows we installed a recommended version of Rtools (Rtools212) but the linker fails with the messages below. ... g++

I have some images of bugs (insects) with many bugs in each image. I want to count the number of bugs and to have an estimate of the area of each one. I've tried searching for an R package to do so with no success. Is this a task that I should pursue doing in R or should I restrict myself to specific image analysis software (e.g. ImageJ)?. The reason I consider R would be a good choice is

Hello, Just a quick message to correct what I have said in my previous post.It finally seems not that easy to code small wavelet coefficients to have a good precision, and SPIHT is certainly a very good algorithm for that, -and I know there are SPIHT experts that can make very good SPIHT-based codecs-.I have chosen a new and different approach, the multistage residual coding, so I will try to

Here we use a (custom-made, internal) password propagation system, hooked around 'check password script'. Recently we suffer a network outgage (another one ;-), and the system that take care of password propagation goes offline. + NT domains continue to work, clearly password not propagate + AD domain stop to work (eg, users password change on windows stop to work), because the

Initially out there as #965245. I strongly prefer to build ARM64 packages on non-ARM systems. Something about my main build machine having twice the cores and twice the clock speed. As such after many builds I've managed to generate a set of patches which appear to mostly function to get functioning cross-builds of Xen. These are NOT a 100% solution. Some packaging hacks were needed. In

Hi all, Two days ago I send below post to wine newsgroup with no response. Since I send mail I try to upgrade to wine-cvs version, but, It is a worst solution. Now I got this error: razer@puerto-lobo:~/.wine/drive_c/Sacred$ wine sacred.exe fixme:system:SystemParametersInfoW Unimplemented action: 8192 (SPI_GETFOREGROUNDLOCKTIMEOUT) fixme:system:SystemParametersInfoW Unimplemented action: 8193

Hi, All!! Again about time sync Win and Linux. If there is a way to sync. time of Windoze and my LInux server except "net time \\flash /set /yes". That way works wonderfull and properly, but BAD user of my net DON"T want to remember their passwords.... Does anybody know what I should do? ......,Yours Alex "Flash"
