...I really don't know why. I have found the path by going to the folder and finding the info about the folder, where the location of this is stated. I copy-paste this into the source command. The path for the folder is: When found with the "info about the folder": /Users/gban/Desktop/Methylation analysis/MethylationDataAnalysis But I think it should be: /Users/gban/Desktop/Methylation analysis/MethylationDataAnalysis/1.Normalization_raw_data/ as it is the folder 1.Normalization_raw_data where my data are in. I have tried both paths but it returns with this message every time: > sourc...

Hello, I have an input file: http://r.789695.n4.nabble.com/file/n3700031/testOut.txt testOut.txt where col 1 is chromosome, column2 is start of region, column 3 is end of region, column 4 and 5 is base position, column 6 is total reads, column 7 is methylation data, and column 8 is the strand. I would like a summary output file such as: http://r.789695.n4.nabble.com/file/n3700031/out.summary.txt out.summary.txt where column 1 is chromosome, column 2 is start of region, column 3 is end of region, column 4 is total reads in general, column 5 is total...

...equation for this was: pBH = p*n/i where p is the original p value, n is the number of tests and i is the rank of the p value.

...a query search in character format. When I use efetch, the accession number isn't in a character format, and I'm not sure if the number is accurate, because I get the error: Error in file.exists(destfile) : object 'destfile' not found This is what I tried: UIDs<-esearch( "Methylation" ) accession_numbers = efetch(UIDs, rettype = "acc") How do I obtain only the accession number and is the number accruate? Thank you [[alternative HTML version deleted]]

...analyze the data. There are nine dishes of cells. Three replicates for each treatment combination. So randomly select three dishes for no drug A/no drug B treatment, a second three dishes for drug A only, then last three dishes to add both A and B drugs. After drug treatments, they measure DNA methylation and genes or gene expression as outcome or response variables(two differnet types of response variables). My boss might want to find out net effect of drug B, but I think we can not exclude the confounding effect of drugA. For example, it is possible that drug B has no effect, only has effect when...

Hi All: Greetings, and best wishes from the festive times here at Kolkata, India -- the time of Durga Puja celebrations. I seek your advice as I try plotting lines for my data. The problem: I have created a dataframe that looks like this (name: myFrame): lowest second third fourth highest significance INAS 0.107 0.115 0.123 0.115 0.166 0.000 MMA 0.091 0.107 0.115

David: I believe your response on SO is incorrect. This is a standard OFAT (one factor at a time) design, so that assuming additivity (no interactions), the effects of drugA and drugB can be determined via the model you rejected: For example, if baseline control (no drugs) has a response of 0, drugA has an effect of 1, drugB has an effect of 2, and the effects are additive, with no noise we

Hello all, I would like to introduce our group's new bioinformatics package to you: pathfindR <https://cran.r-project.org/package=pathfindR> This tool is designed to improve pathway enrichment analysis by firstly identifying active subnetworksin differential expression/methylation data using a protein-protein interaction network. It then performs pathway enrichment analysis (Over-Representation Analysis). By utilizing the interaction information, the tool identifies most of the involved pathways. pathfindR also creates pathway diagrams with the involved genes colored by chan...

Hi I apologise for this question as it really must be a FAQ. Unfortunately, I can't find the answer and I'm tired of looking at endless google results A colleague of mine works for a state government department that has a policy against open source software or software tainted by open source. Other government departments in the same state use R but this particular department is driven
