similar to: To add text in a matrix

I've ported somebody else's rather cumbersome Matlab model to R for colleagues that want a free build of the model with the same type of I/O. The Matlab model reads a text file with the initial parameters specified as: C:\Data\Carluc\Rport>more Params.R # Number of years to simulate nYears = 50; # Initial year for graphing purposes year0 = 1970; # NPP/GPP ratio (cpp0 unitless) fnr =

Introduction: We would like to add new keyword to 'sdiv'\'udiv' instructions i.e. 'no-overflow'. This is the updated solution devised in the discussion: http://lists.llvm.org/pipermail/llvm-dev/2017-October/118257.html The proposed keywords: "nof" stands for 'no-overflow' Syntax: <result> = sdiv nof <ty> <op1>,

Hi, I want to put text on a plot containing something like: a = b^2 = <squared numeric value of b> using bquote. Example: mu = 5 plot(1:10,1:10) text(2,8, bquote(delta == mu^2)) # This works text(2.5,8, bquote(phantom(0) == .(mu^2))) # but is unpredictable text(2,8, bquote(delta == mu^2 == .(mu^2))) # This doesn't work The last text function returns the error:

Dear all, Suppose I have a dataset like below, then I take for example, 100 random sample "class" variable where contains "yes" and "no" respectively, 70% and 30%. I need a new 100 random sample from mydat dataset, but I can't get the result. Thanks you very much for any helps. Best, Muhammad Subianto mydat <- data.frame(size=c(30,12,15,10,12,12,25,30,20,14),

Hi, I have what I think is a simple question/issue but I have unable to find the answer for it either in the R-manual or by browsing the web. I would like to know if there is a "mode" function in R, such that from a vector or matrix the function returns the most common value. In other programs I use (such as Matlab) I can have for exampe a 3X3 matrix A, A=[1 2 3; 1 3 2; 3 3 2] and I

Hi all, Appologies for the rather basic IO question but I am rather new to R... Migrated from IDL/Matlab recently. I have a rather simple Fortran control file (sigh...) that I am trying to parse and read using R. My problem is that the file's format is somewhat flexible. Imagine: --- 1> 39 1901 2> 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 3> 22 24 26 28 30 32 34 36

Hello veryone, I am interested in the diffusion of particles inside a sphere, and its release through a small pore on the sphere surface. Unfortunately, I have not found the way to do this in R. Could you help me? Thank very much in advance for your help

Hello, I discovered R two years ago and thanks to the R-community I managed to write some scripts to analyze my data stored in mysql databases. The only problem is that I am the only one using R in the lab. Colleagues mainly use Matlab (but not with mysql, only with text files) but regularly come to me to get data treated with R-scripts !!!. To allow the use of my scripts by other people, my

I have rsync daemon running on a fedora core 4 box that I am trying to use as a backup server for my web sites. I dont have shell access on my web host so will need to run a cron job to do the backups, which is what I want to do anyway. For testing purposes however I am using a php script using the "system()" function so I am getting some feedback. In my rsyncd.conf file I have the

Hi, All: How might one test Matlab and perl code during "R CMD check"? I ask for two reasons: First, the "fda" package exists in both R and Matlab, and it would help if we could run test examples in Matlab as part of "R CMD check". I tried "R.matlab", but could not get it to work in that context. Second, I have professional

Hi all, I've noticed that many computational neuroscience research groups use MATLAB. While it's possible that MATLAB may have some features unavailable in R, I suspect that this may instead simply be a case of costly tradition, where researchers were taught MATLAB as students and pay for it as researchers because it's all they know. I'd like to attempt to break the cycle by

The other day, CNN had a story on working at Google. Out of curiosity, I went to the Google employment web site (I'm not looking, but just curious). In perusing their job posts for statisticians, preference is given to those who use R and python. Other languages, S-Plus and something called SAS were listed as lower priorities. When I started using Python, I noted they have a portion of the

Hi All, (I have a degree in math, but I am too embarassed to ask my colleagues, so here goes:) I would like to get a vector normal (orthogonal) to a plane formed by two other vectors. In matlab I do this: v1 = [.4, .6, .8]; v2 = [.9, .7, .2]; nn = cross(v1,v2) (gives ~[-.48, .65, -.24] if I do R> cross(v1, v2), I get .94. Huh? Thanks for all your help, again. W

When I have to enter a very large matrix into the R console, I can make use of the continuation feature in the console to enter the matrix in pieces (e.g., on a row by row basis). So, for example, the console would show the "+" sign for continuation lines - something like what I've written below: a=matrix(c(0,20,50, + 0.05,0,0, + 0,0.1,0), + 3,3,byrow=T) (obviously, for a

Estimados. Hace un tiempo que tengo una duda, estaba pensando en los problemas como optimización de costos, donde hay varias alternativas y librerías, pasando por soluciones inspiradas en energía, genética o algo matemático como matrices y álgebra. Luego aparecen tensorflow, cntk, y otros tantos, de los cuáles https://keras.rstudio.com/ ofrece alternativas para mezclar los mundos por decirlo de

Tienes razon de que hay una serie de paquetes que lo usan, pero me da que vienen impulsados por Rstudio desde el paquete tidyverse... Yo me resisto a usarlo.
