Hi, First of all, I would like to introduce myself as I will probably have many questions over the next few weeks and want to thank you guys in advance for your help. I'm a cancer researcher and I need to learn R to complete a few projects. I have an introductory background in Python. My questions at the moment are based on the following sample input file: *Sample_Input_File*

Hey, I just googled my error and many things came up. I followed the leads and read the ?read.delim page; I tried changing header = TRUE, and row.names = TRUE-- but I've still been having trouble fixing it, so I would greatly appreciate any help you can provide. Here is my code: rm(list=ls()) source("../../functions.R") uncurated <-

Hi, My project is set up the following way: root directory contains the following folders: folders: "Breast_Cancer" AND "Colorectal_Cancer" AND "Lung_Cancer" AND "Prostate_Cancer" I want to create a file, call it: "repeating_functions.R" and place it in the root directory such that I can call these functions from within the sub-folders in each

Hi-- I have three columns in an input file: MONTH QUARTER YEAR 2012-07 2012-3 2012 2001-07 2001-3 2001 2002-01 2002-1 2002 I want to make output like so: MONTH QUARTER YEAR 07 3 2012 07 3 2001 01 1 2002 I was having some trouble getting the regular expression to work. I think it should

Hi, I'm a new user of the R package, and I need to generate recurrence plots for a set of 56 time series data. The package tseriesChaos has the function "recurr" that gives a plot. But what I really need are the recurrence plot parameters that are calculated from each plot (like %recur, %det, trend, etc...) and that can be stored dynamically in a output file for all the 56 datasets.

Hi, I was reading a paper published in JCO "Prediction of risk of distant recurrence using 21-gene recurrence score in node-negative and node-positive postmenopausal patients with breast cancer treated with anastrozole or tamoxifen: a TransATAC study" (ICO 2010 28: 1829). The author uses a method to estimate the 9-year risk of distant recurrence as a function of continuous recurrence

Hello, I am an absolutely beginner with regards to R, so forgive me for my potentially very stupid questions. I have been attempting to create recurrence plots using R. The data I am using is based on a mutually exclusive and exhaustive coding scheme with over 40 individual codes which can be assigned to 6 higher order categories. When I carry out the usual rqa command, my plot is pretty much

Hey, I'm trying to match patient identifiers from two separate input files, and then add information from one of the input files to the corresponding output file. I'd greatly appreciate any help! More specifically, Input_File_1 has a column header "bcr_patient_barcode" Input_File_2 has a column header "Barcode" and a column header "Batch" I want my script

Thanks Sanjoy. > To be pedantic, "var[i<<1]" is not an add recurrence, but "&var[i << > 1]" is an add recurrence. I'll assume that's that you meant.

Is there a document describing the guts of SCEV anywhere? I have a simple question. When looking at a linear SCEVAddRecExpr with a constant step recurrence (that is, getStepRecurrence returns SCEVConstant), is the constant in terms of bytes or in terms of "index," in that the byte offset is calculated by taking the step and multiplying it by the data size of any memory operation its

Hello all, I wanted to get some feedback on this patch for ScalarEvolution. It addresses a performance problem I am seeing for simple benchmark. Starting with this C code: 01: signed char foo(void) 02: { 03: const int count = 8000; 04: signed char result = 0; 05: int j; 06: 07: for (j = 0; j < count; ++j) { 08: result += (result_t)(3); 09: } 10: 11: return result; 12: } I

Hello. Could you please tell me why the first loop of the following program (also maybe the commented loop) doesn't get vectorized with LoopVectorize (from a recent LLVM build from the SVN repository from Jun 2018)? typedef short TYPE; TYPE data[1400][1200]; void kernel_covariance(int m, int n, TYPE mean[1200]) { int i, j, k; for (j = 0; j < m; j++) { mean[j] =

Hi, > Is there a document describing the guts of SCEV anywhere? If you're looking for theoretical background of SCEV (chains of recurrences algebra), you may take a look at this article: http://citeseer.ist.psu.edu/vanengelen00symbolic.html I'm not aware of any LLVM-specific document describing SCEV. > I have a simple question.

My interest in icalendar is more on the ical generation side instead of the ical parsing side. As such, I did a bit of work on a tzinfo mixin that will generate the timezone rules based on the tzinfo gem. This lets you do the following: estart = DateTime.new(2008, 12, 29, 8, 0, 0) eend = DateTime.new(2008, 12, 29, 11, 0, 0) tstring = "America/Chicago" tz =

Hello. I'm not able to vectorize this simple C loop doing basically what could be called predicated sum-reduction: #define NMAX 1000 int colOccupied[NMAX]; void Func(int N) { int numSol = 0; for (int c = 0; c < N; c++) { if (colOccupied[c] == 0) numSol++; } return numSol; } The compiler

Hi, I'm just finishing up an R package and I was wondering if anyone knows how to include institution name in the "Description File." That is, my current Description File looks like: Package: curatedCancerData Type: Package Title: Cancer Gene Expression Analysis Version: 1.0 Date: 2011-12-24 Author: Benjamin F. Ganzfried, et al.

Hi, I read on a paper the below statement, don't know how that was calculated. Basically, there are 2 continuous variables x1 and x2, as independent variable for predicting cancer recurrence. So this is a survival analysis. Now the author try to check the correlation between x1 and x2. He calculated Spearman rand correlation (~0.22), then he had the following statement: "Only
