Dear all, I'm a newbie in R. I have a 45x2x2x8 design. A dataframe stores the metadata of trials. And each trial has its own data file: I used "read.table" to import every trial into R as a dataframe (variable). Now I dynamically ask R to retrieve trials that fit certain selection criteria, so I use "subset", e.g. tmptrialinfo <- subset(trialinfo, (Subject==24 &

Dear R Users, I have created a 1500 x 20000 data frame - DataSeq. Each of the 1500 rows represents a data sequence. I have another data frame iData that stores the information of these 1500 data sequences in the same order, for example, condition, gender, etc. If I use "subset" to select certain groups within iData according to some criteria that I have set, e.g. condition, gender Then

Hello all, Probably my concepts about the data.frame and matrix and array in R are not clear, I need some clarification to help me understand them better. >M <- read.table("test1.csv",sep=",",row.names=NULL,header=T) gives me: M as M1 M2 M3 M4 M5 M6 M7 M8 M9 M10 1 9 11 14 15 18 20 20 20 20 20 2 3 4 8 9 11 12 14 15 15 15 3 4 5 8 8 9 9 9 9 9 9 4 4

NFC: Restructuring LoopRoration.cpp to create Loop Rotation Pass with Loop Rotation Utility Interface ============================================================================= Why this NFC change? ================= The existing LoopRotation.cpp is implemented as one of loop passes instead of being a utility. The user cannot easily perform the loop rotation selectively (or on demand) under

Hi all, let's say I have matrix People Desc Value Mary Height 50 Mary Weight 100 Fanny Height 60 Fanny Height 200 Is there a quick way to form the following matrix? People Height Weight Mary 50 100 Fanny 60 200 (Assuming I don't know the length of people/desc and let's say these are characters matrix.. I tried

Dear R users, I have been using a dynamic data extraction from raw files strategy at the moment, but it takes a long long time. In order to save time, I am planning to generate a data set of size 1500 x 20000 with each data point a 9-digit decimal number, in order to save my time. I know R is limited to 2^31-1 and that my data set is not going to exceed this limit. But my laptop only has 2 Gb and

I think I am overlooking a call or concept in R to help me easily and quickly restructure my data.frame:   Sometimes the data I receive looks like: VariableName, Run1, Run2, Run3, Location temp,               15.0,  16.0,  17.0, There   And other times it looks like: VariableName, Run, Location temp,               17.0, There   I would like to use the header information in order to be able to

I'm having trouble restructuring data from the rwars package into a dataframe. Can someone help me? Here's what I have... library("rwars") library("tidyverse") # These data are json, so they load into R as a list people <- get_all_people(parse_result = T) people <- get_all_people(getElement(people, "next"), parse_result = T) # Look at Anakin

The current name of gnome-window-decorator is wrong. There's nothing gnome specific in that code. I'll go a head and change the name to gtk-window-decorator later today. I'm also going to split the gnome configure option into a gtk and a gnome option as the only gnome specific code that exist in the tree is the compiz-window-manager module which is used to integrate with the gnome

Hello, vegMeans <- by(SoilVegHydro[3:37] , SoilVegHydro$Physiogomy, mean) vegSD <- by(SoilVegHydro[3:37] , SoilVegHydro$Physiogomy, sd) write.table(vegMeans, file="A:\\Work_Area\\Steve\\Hydrology_Data\\data\\vegMeans.txt") Error in as.data.frame.default(x[[i]], optional = TRUE, stringsAsFactors = stringsAsFactors) : cannot coerce class '"by"' into a

Dear R users, I have 1 data.frame of 1500x80 - data1. I found out that there are a few cells of data that I have misplace, and I need to fix the ordering of them. In an attempt trying to swap column 22 & 23 of the Subject with misplaced data, I did the following: > data2 <- data1 > subset(data1,(Subject==25 & Session==1))[,22] <- subset(data2,(Subject==25 &

Hi folks, I am new to the list and relatively new to R. I am trying to unstack data "arraywise" and could not find a convenient solution yet. I tried to find a solution for the problem on help archives. I also tried to use the reshape command in R and the reshape package but could not get result. I will illustrate the case below, but the real dataset is quite large so that I would

Hi all, I'm having a problem restructuring my data the way I'd like it. I have data that look like this: Candidate.ID Specialty Office Score 110002 C London 47 110002 C East 48 110003 RM West 45 110003 RM

Dear R users, I have copied for following table from an article on "Using confidence intervals in within-subject designs": Subject 1sec 2sec 5sec 1 10 13 13 12.00 2 6 8 8 7.33 3 11 14 14 13.00 4 22 23 25 23.33 5 16 18 20 18.00 6 15 17 17 16.33 7 1 1 4 2.00 8 12 15 17 14.67 9 9 12 12 11.00 10 8 9 12 9.67 I rearranged the data this way:

Hi, I've got a question regarding the restructering of a data set. What I have are municipality zip-codes and the names of 5'000 built-up areas within municipalities. The following example shows, what I would like to do: Input (Zip-Codes and Names): # CODE NAME #1 3 aaa #2 3 aab #3 3 aac #4 4 bba #5 4 bbb #6 4

Dear R users, I'm trying to plot 45x8 graphs on the same pdf / device for the sake of visual comparison. par(mfcol=c(45,8)) par(mai=c(0,0,0,0)) In ?title, I can see there are cex and font settings: I set cex = 0.01 and font = 1: it is still very large, and then I tried setting font < 1, e.g. font = 0.5, Then I get an error: Error in title(paste(Ppercent, "% ",

Hey folks, Could we have a talk about the website homepage layout? Here is a tentative sketch I am working on for the a new website theme: https://centos.gitlab.io/artwork/centos-web/jekyll-theme-centos-base/documentation/#the-page-basehome-layout In this layout: Are "News and Events" and "Blog Posts" redundant sections?? Does it make sense to present only extracts from

Dear all R users, I am going to use R to process some of my physiological data about eye. The problem is the recording machine does not sample in a reliably constant rate: the time intervals between data sampled can vary from 9msec to ~120msec, while most around in the 15-30msec range. The below is a fraction of a single data file of a trial: Time CursorX CursorY Pupilsize 1811543 -1 -1 -1

Hello, I am having trouble creating a (1000,3,201) array in R from a data set created within the same script. My problem is that I want to take a matrix that is 1000x603 (called "landmat") and separate this into 201 separate (1000x3) matrices. My problem is when I try to do particular combinations of the columns. I want to take the first 3 columns of "landmat" and create

Alain, That looks great and the sections make sense as you've described them. As far as News and Events and Blog, I do think they're the same thing but I kind of like the idea of calling it News and Events vs Blog.
