Hello, I have a matrix with 6 columns and 12 rows. I want to extract out those IDs (rownames) from my matrix which have a negative values. For each ID(row) if the negative value is even under 1 column it needs to be extracted out. I will be grateful for any correct suggestion. Thanks Manisha Here is the matrix that I am working on: ID A B C D E F 1 -4.18972 -3.8946

Hello, I will appreciate any suggestion for this simple problem. I have a matrix of characters "A", "P", "M". I want to convert those characters to integers 0,1, 1 respectively. I am using the following R statements: exprs.new<-gsub("P",1,exprs) exprs.new1 <- gsub("A",0,exprs.new) exprs.new2 <-

Hi, I am having troubles with creating an eSet and would appreciate any help on the following problem. I am trying to create an eSet using the following code pd <- read.table(file="pdata.txt",header =TRUE,row.names=1); colnames(pd) <- c("type","tumor","time","id"); pdN <- list(type =

Hi, I have a query regarding usage of hist (histogram) function in R. I have a data where the range of the x -axis is from 0.0-1.0. When I use hist the ticks on the x-axis it gives me by default is at 0.0,0.2,0.4,0.6,0.8 and 1.0. If I want more ticks such that the x-axis has 0.0,0.1,0.2,0.3...till 1.0 what parameter should I use in the hist function? Thanks manisha

Full_Name: Manisha Desai Version: 1.3.0 OS: UNIX Submission from: (NULL) (156.111.36.213) There may be a bug in the table command. The value of 0 does not appear to show up (at least in this version of R). The following is an example: > blah<-c(rep(1,100),rep(0,100)) > table(blah) Gives the following: blah 1 100 Doing a summary shows that blah does contain values of 0. >

Hello, I am trying to calculate the median of numbers across each row for the data shown below , with the condition that if the number is negative, that it should be ignored and the median should be taken of only the positive numbers. For eg: data is in Column A,B,C. Column D and E demonstrates what I want to get as answer A B C Median median value -13.6688115 -32.50914055

Hello, I am trying to do a spearman correlation. My data has tied values. To overcome this issue, I am adding some random noise (values) to my original data. However when I add the random noise to the data, the final matrix does not show the new values. I guess the reason being that the noise I add is very small and the full value including the decimals gets truncated to show only the value

Dear r-help list members, Is there an R package to compute the power and sample size of generalized linear models with categorical independent variables? I am especially interested in the negative binomial error model. Failing this, is there any package outside of R that does this kind of calculation? Thanks!

Dear R-list, In the R-book, p.464, Michael Crawley recommends that error bars for bar plots of normally distributed continuous response variables with categorical explanatory variables be given by 1/2 of the least significant difference, where the least significant difference is defines as qt(0.975,degrees_of_freedom)*standard_error_of_the_difference. The idea is that the above quantity

Manisha, I'm still here. :-) Here's the function: // Returns the average power level in the given signal float getPower(signed short int *signal, int numSamples) { int i; float amp; float powerSum = 0.0f; for (i = 0; i < numSamples; i++) { amp = (float) abs(signal[i]); powerSum += amp * amp; } return powerSum / (32768.0f * 32768.0f *

Dear R-help-list, I have a problem in which the explanatory variables are categorical, the response variable is a proportion, and experiment contains technical replicates (pseudoreplicates) as well as biological replicated. I am new to both generalized linear models and mixed- effects models and would greatly appreciate the advice of experienced analysts in this matter. I analyzed the

I have a question regarding the adf.test command in the tseries library. I have a vector of time series observations (2265 daily log prices for the OEX to be exact). I also have this same data in first-differenced form. I want to test both vectors individually for staionarity with an Augmented Dickey-Fuller test. I noticed when I use the adf.test command from the tseries library, the general
