How to transform this data frame to a matrix formed as follow: 1. the colomn 5 is the comumn (string) 2. the colomn 5 row 3. the data are the colomn x. I aim to draw barplot later using the matrix.

Hi i'm a french medical student, i have some data that i import from excel. My colomn of the datafram are the localisations of metastasis. If there is a metatsasis there is the symbol "_". i want to exclude the row without metastasis wich represent the NA data. so, i wrote this mela is the data fram mela1=ifelse(mela[,c(11:12,14:21,23,24)]=="_",1,0) # selec...

Dear all, I am trying to merge two data frames based on a common column but for this common column both data frame do not have the same length and associated information. I checked previous exemples in the list but was not able to apply them in my case... Is someone know how to do that? Below is my code with the expected result: # data frame 1 Id1 <- c(1,1,1,2,2,2,3,3,3) Habit1 <-

Hi everyone, I am having some problems with making a new colomn wit data in it. I have this one column named: Fulfilled Fulfilled 1 1 0 1 1 1 1 0 0 1 And now I would like to add another colum to my .csv file ("Finished") In this "Finished" column I would like to have "Yes" or "No". Where in colomn "Fullfilled&q...

Hi All I have a dataset of 200 columns and 1000 rows , there are 3 repeated values under each column (7,8,10). I wanted to calculate the frequency of each value under each column and then apply the function maf () given that the frequency of each value is known. I can do the analysis step by step like this :- > Values A B C ... 200 1 7 10 7 2

...he frequency of 0 values should also be calculated for the maf to be calculated correctly. ________________________________ From: Bert Gunter <bgunter.4567 at gmail.com> Sent: 09 November 2017 23:51:35 To: Allaisone 1; R-help Subject: Re: [R] Calculating frequencies of multiple values in 200 colomns [[elided Hotmail spam]] "For example, if I have the values : 1 , 2 , 3 in each column, applying Tabulate () would calculate the frequency of 1 and 2 without 3" Huh?? > x <- sample(1:3,10,TRUE) > x [1] 1 3 1 1 1 3 2 3 2 1 > tabulate(x) [1] 5 2 3 Cheers, Bert Bert Gunt...

Hello, I have some "stupid" problems managing "date" data. I have a colomn "date", which I converted from a character representation: for example: a="26/02/06" date=strptime(a,format="%d/%m/%y") For one part of the analysis, I'm interested only in the month and the year, so I did: m.y=strftime(date,format="%m/%y") This retu...

...nsisting of 17 rows). Here's an example The vector: v <- c(f,a,e,d,m,o,e,f,i,n,e,i,b,a,o) The dataset's columns consist of the following values d[,1] <- c(a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q) d[,2] <- 1:17 So I want to end up with a vector that consists of the values of the second colomn, when the value of the vector matches the value of the first colomn. Thus, I aim to end up with a vector with the following values c(6,1,5,4,13,15,5,6,9,14,5,9,2,1,15) Help is appreciated! ------------------------------------------------------------------------------ De informatie opgenomen in d...

Hi, I am new to R, I am doing quantile normalization with a dat matix of 384X124 and I find that while computing the quantile normailzation it introduces 'NA' into some of the cells, can someone help me to overcome this problem ? This is the command that goes like upto g62 for 124 colomns >g1 <- normalize.quantiles(exprs(MSExpr[,1:2])) For a small set of data there is no problem, but for a large set of data, it introduces "NA" in the place where it is suppose to geneerate data .

Thus, I want to get a draw with 3 colors for values 0 , 0.2 and 0.4 The probleme is that when I use points function; it plots to me lines and not simpe points.

...my data) > 3. No correlation structure in the residuals. In this case, I'll use drop1 on the original model, and test various corARMA again for the new model. And the cycle from step 1 to 3 goes on. try1$resid (or resid(try1)? I forget) would give me two columns of residuals, the first colomn being residuals and the second being subject-specific residuals. I want to analyze the residuals using arima, so which colomn should I use? In my imagination (maybe a silly idea), considering all possible time lags between variables, to cope with the regression above, I would make pilot pairwise...

Hi I have a code that calculate maximisation using optimx and it is working just fine. I want to extend the code to run several colomns of R_j where j runs from 1 to 200. If I am to run the code in its current state, it means I will have to run it 200 times manually. May you help me adjust it to accomodate several rows of R_j and print the 200 results. ***Please do not get intimidated by the maths in the code.*** my code ######...
