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 <- cbind(dataframe$label, binarize(dataframe[,-1])) but then I lose my header (names).............ho...

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.

...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...

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...

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

...ness and a little less precision (residual coding is applied on "sub" wavelet images or orders and I take advantage then of the neatness the wavelet 5/3 filterbank can have).The entropy coding schemes for each parts: wavelet coefficients, residuals, are also near optimal as with the best (binarization +) context modeling + arithmetic coders, except for the DC parts where the compression scheme is not optimal, can win 0.7Ko per file in average with the best arithmetic coders. The NHW codec is also (really) faster in return, -it also uses a "direct" discrete wavelet 5/3 transform...

...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.

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

..., so there might be a wired reply from me saying that I have found the answer from the R source code, it was sent from me last week. Hopefully, this reply will not cost another week to post:) As a side note, I like the idea that defining a macro for sortedness, and I can see why we can only have a binary answer for NO_NA (since the return value is actually bool). For making the code more readable, and for possibly working with the future R release, is it possible to define a macro for NO_NA function in RInternal.h? So if there is any change in NO_NA function, there is no need to modify the code. A...
