hello everyone, i'm new to R, so i hope you dont mind a fairly basic R question. we're using R to manipulate the results of SQL queries and create an HTML output. I'm starting with a table that looks essentially like this: Name Field1 Field2 John value1 value2 Jane value3 value4 My table is stored as a dataframe. I'd like to efficiently produce an

Hi, Does anyone know how to do a coord_trans() in which the y-axis is tranformed into (for example) -1000/y?

Greetings, I'm learning R and I'm stuck on a basic concept: how to specify a logical condition once and then perform multiple transformations under that condition. The program below is simplified to demonstrate the goal. Its results are exactly what I want, but I would like to check the logical state of gender only once and create both (or any number of) scores at once.

Dear all,?I am trying to fit a multiple linear regression model with a transformed dependant variable (the normality assumption was not verified...).?I have realised a sqrt(variable) transformation...?The results are great, but I don't know how to interprete the beta coefficients... Is it possible to do another transformation to get interpretable beta coefficients to express the variations in

Hi, Is the number of lines that can be displayed in R GUI limited? When I do a Fourier Tranform of 4000 data points, I can only see the last 300 or so of it. I need to see all of it. How is this possible?

...need to transform the row names into date format. But I do not manage. Therefore, for an example, I manage to write this : datetest<-"06/01/2001" datetest<-as.Date(datetest,"%d/%m/%Y") datetest<-as.numeric(datetest) to get 11328. But I do not obtain the inverse tranformation : datetest<-as.Date(datetest,"%d/%m/%Y") How do we get this please ? Thanks a lot for your solution. Pierre. [[alternative HTML version deleted]]

Hi, Is it possible to recieve an xml repsonse from my rails app, and then, client side, inject the xml into the page without reloading and have it apply an xslt? Like an AJAX call, but ajax is unavailable to me. My very limited understanding suggests that xslt is only done at run time in safari at least. If I can''t get thsi to work the other option I''ve thought of is to use

Dear metafor users, I am working on a meta-analysis of reliability and the correlation associations. I need some help about conducting categorical moderators variables. Questions 1: How to conduct the weighted ANOVAs assuming a mixed-effects model on the tranformed alpha coefficients/the tranformes correlation coefficients for the categorical moderator variables? Questions 2: How to

I am dealing with a seasonal time series data. In order to ger rid of the nonstationarity of the variance, i need to perform power tranformation to the data and choose the best lambda value. In Mass package, there is a function called 'boxcox' to do power tranformation but it only deals with linear model. Is there anyone who knows the other function that cannot perform power tranformation to time series data? Thanks! -- View this...

Hi, I have a data.frame with the following variable: $ xx :Factor w/ 66 levels "01.02.2006","01.03.2006",..: 3 3 3 3 3 3 3 3 3 now I?d like use "as.date" on it - if I comprehend the instructions on http://finzi.psych.upenn.edu/R/library/base/html/format.Date.html it should work like this: as.date(xx, "%d.%m.%Y") - but it doesn?t... the survival Package

Hi All, I am (almost) successfully using apply() to apply a function recursively on a data matrix. The function is question is as.genotype() from the library 'genetics' apply(subset(chr1, names$breed == 'lab'),2,as.genotype,sep ="") Unfortuantely apply puts it's results into a matrix object rather than a data frame, tranforming my factors into numerics and

Hi All, With the "https://gcc.godbolt.org/z/yBYTrd" case . the atomic is converted to non atomic ops for x86 like from xchg dword ptr [100], eax to mov dword ptr [100], 1 the pass is responsible for this tranformation was instCombine i.e InstCombiner::visitAtomicRMWInst which converts the IR like %0 = atomicrmw xchg i32* inttoptr (i64 100 to i32*), i32 1 monotonic to store atomic i32 1, i32* inttoptr (i64 100 to i32*) monotonic, align 4 which is valid for relax(monotonic) and release ordering as per the code...

Dear, LLVM developers. We appreciate your interest. We contacted to solve the problem of setting the pass. Our pass setup process is as follows: 1. Add pass subdirectory from CMakeLists.txt in llvm/lib/Tranform 2. Change CMakeLists.txt in llvm/lib/Transform/pass 3. Run make in llvm/build/lib However, the desired pass file was not created. There were no errors in the make process. Installed

...39; to 'column', the heatmap will be always be red. I think this is because, there's very large values in the matrix (gene Actb), while the most are just very small. Thus, the color will be very ugly. I just wonder, how to set the color to make the heatmap look better? I have tried log-tranformation on the matrix and it's better now. But I do want to know if you have better ways to set the color span manually and make the heatmap look better without any log-transformation? Thanks in advance! Best, Hua

What is the best way to pick a prebuffering length for a streaming audio application using UDP transport? I'm using Speex in a VoIP application with RTP transport, currently with a fixed 500ms prebuffer on the playback side. However, I'd like something a bit more adaptive to accomodate high-jitter connections. For example, in one test configuration there is a very low average

Hi, I am new to use R, but can anyone tell me how to tranform quarterly data to monthly data? I know SAS has this procedure, so may I assume it is also available in R? Thanks a lot! Ed

Hello, I'm trying to tranform a numeric vector into a character vector. > x=c(2.00,1.20,5.00,6.56) > y= as.character(x) > y [1] "2" "1.2" "5" "6.56" What I want is : [1] "2.00" "1.20" "5.00" "6.56" Does someone know how to do this please ? Benoit Bruneau
