Hi I needed some help with ANOVA I have a problem with My ANOVA analysis. I have a dataset with a known ANOVA p-value, however I can not seem to re-create it in R. I have created a list (zzzanova) which contains 1)Intensity Values 2)Group Number (6 Different Groups) 3)Sample Number (54 different samples) this is created by the script in Appendix 1 I then conduct ANOVA with the command >

Hi I have found a little problem with an R script. I am trying to merge some data and am finding something unusual going on. As shown below I am trying to assign (MatchedValues[Value2,Value]) to (ClusteredData[k,Value]) which are two separate dataframes. 1) By the following command you can see that the value im transferring is 481844.03 > MatchedValues[Value2,Value] [1] 481844.03 6618

Hi I am trying to create a column in a data frame which gives a sigificane score from 0-7. It should read values from 7 different colums and add 1 to the counter if the value is <=0.05. I get an error message saying Error in if (ALLRESULTS[i, 16] <= 0.05) significance_count = significance_count + : missing value where TRUE/FALSE needed The script is included below it works if i

Hi I have tried many attempts but cant get the loop right, as I am not a strong programmer. What I am basically trying to do is compare 2 spreadsheets. The problem is that one of them only contain a portion of the overall data (TESTSAMP), where the other has a full datasetFULLSAMP. From the complete set I would like to remove the rows of data which are not in the TESTSAMP. Column 1 contains the

Hi i am using a script which involves the following loop. It attempts to reduce a data frame(zz) of 95000 * 41 down to a data frame (averagedreplicates) of 95000 * 21 by averaging the replicate values as you can see in the script below. This script however is very slow (2days). Any suggestions to speed it up. NB I have also tried using rowMeans rather than adding the 2 values and dividing by 2.

Hi I am attempting to use plsr which is part of the pls package in r. I amconducting analysis on datasets to identify which proteins/peptides are responsible for the variance between sample groups (Biomarker Spoting) in a multivariate fashion. I have a dataset in R called "FullDataListTrans". as you can see below the structure of the data is 40 different rows representing a

Hi I am trying to create a loop which averages replicates in my data. The original data has many rows. and consists of 40 column zz[,2:41] plus row headings in zz[,1] I am trying to average each set of values (i.e. zz[1,2:3] averaged and placed in average_value[1,2] and so on. below is my script but it seems to be stuck in an endless loop Any suggestions?? for (i in 1:length(average_value[,1])) {

Hi I have done ANOVA on a dataset (See Below) but am having problems retreiving the p-value. I am assuming that Pr(>F) is the p-value but cannot get this value or in fact any other value (e.g. DF) from the summary.Any suggestions?? I have tried sum<-summary(zzz.aov) > sum$Pr(>F) Error: unexpected '>' in "sum$Pr(>" > sum$"Pr(>F)" NULL >

Hi I am analysing a dataset of 40 samples each with 90,000 intensity measures for various peptides. I am trying to identify the Biomarkers (i.e. most significant peptides). I beleive that PLS with jack knifing, or alternativeley CMV(cross-model-validation) are multivariateThe 40 samples belong to four different groups. I have managed to conduct the plsr using the commands: BHPLS1 <-

Hi When I call for the loadings of my plsr using the command, x <- loadings(BHPLS1) my loadings contain variable names rather than numbers. >str(x) loadings [1:94727, 1:10] -0.00113 -0.03001 -0.00059 -0.00734 -0.02969 ... - attr(*, "dimnames")=List of 2 ..$ : chr [1:94727] "PCIList1" "PCIList2" "PCIList3" "PCIList4" ... ..$ : chr

Hi I am attempting to do a loadings plot from a plsr object. I have managed to do this using the gasoline data that comes with the pls package. However when I conduct this on my dataset i get the following error message. >plot(BHPLS1, "loadings", comps = 1:2, legendpos = "topleft", labels = "numbers", >xlab = "nm") Error in

Hi I have implented boxplots in my script to create box plots BoxplotsCheck <- readline(prompt = "Would you like to create boxplots for any Feature? (y/n):")   if (BoxplotsCheck  == "y"){     BoxplotsFeature <- readline(prompt = "Which Feature would you like to create a Boxplot for?:")     BoxplotsFeature <- as.numeric(BoxplotsFeature)     BoxplotsData

hii, i am trying to upload some files to filesystem using rails application when i use small size file everything is perfect but i when goes for larger files i got error this is my code #this model file class DataFile < ActiveRecord::Base def self.save(upload) name = upload[''datafile''].original_filename directory = "//192.168.147.17/Smruti/streams" #

Dear list: I'm using bwplot to compare concentrations by location and treatment as in: # using built in data bwplot( conc ~ Type : Treatment, data = CO2 ) I would like the order of the plots to be: 3,4,1,2. I can't seem to figure this out with index.cond or permc.cond. Any help is appreciated! Brad Eck [[alternative HTML version deleted]]

Hi, I''ve upgraded my shorewall version from 2.0 to 2.2.1 using the .tgz I followed the instructions for upgrade and got a warning when running shorewall check on /usr/share/shorewall/action.DROP and action.Reject using "dropNonSyn" while that has changed to DropNotSyn . I manually copied over action.DROP from the source tree. Question: Are there more files to check ? Even

I''m struggling understanding the model view of a combined model. Take the following: class P4 < ActiveRecord::Base has_many :p4_priorities end I figured out the naming and referencing of the sub models (i.e. P4.p4_priorities - seems simple enough but I had weird issues related to it). I''m all ok except that I am having issues with how to reference a
