similar to: Merging data frames on two conditions

Hi All I have a vector of about 15 million numbers which I would like to plot. The goal is the see the distribution. I tired the usual steps. 1. Histogram : never gets complete my window freezes w/out log base 10 2. Density : I first calculated the kernel density and then plotted it which worked. It would be nice to superimpose histogram with density but as of now I am not able to get this

Hi Guys I am want to join to strings in R. I am using paste but not getting desirable result. For the sake of clarity, a quick example: > a="Bio" > b="iology" > paste(a,b) [1] "Bio iology" *There is a SPACE in the word biology which is what I dont want * Thanks, -Abhi [[alternative HTML version deleted]]

Hi All I have a data frame in which there are 4 columns . Column 1 : name Column 2-4 : values I would like to calculate mean/Standard error of values in column 2-4 and store them in column 5,6 respectively. I have done the following but doesn't seem to work mean_N_SE <-function(x) { name <- x[1] vals <- c(x[2:4]) temp_mean <- mean(vals) SE <- sqrt(var(x)/length(x)) }

Hi Guys I am trying to read a bunch of files in the loop but pipe function which I use to cut few columns is somehow unable to interpolate the file variable. eg: > file="check.txt" > data <- read.table(pipe("cut -f 2,3 file"), sep="\t", col.names=c('pos','cov') ) cut: file: No such file or directory how can I pass variable file to pipe

Hey Guys I want to divide(numerically) all the columns of a data frame by different numbers. Here is what I am doing but getting a weird error. The values in each column are not getting divided by the corresponding value in the denominator vector instead by the alternative values. I am sure I am messing up something. Appreciate your help -Abhi head(counts) WT_CON WT_RB MU_CON

Hi Guys I am back with another thing that's puzzling me. I am creating contingency tables but then I want to filter out certain columns and also find if any entry in the table is 0. Example: gts labels A1 B2 G3 1 21 127 120 2 23 112 0 Here I want to remove B2 column from this table and also if any entry is 0 in this case G3 second row. Missing out on how to do

Hi All I have a data frame in which on the columns is a factor with following levels Levels: M006 M0114 M0379 M0432 M0823 M1012 M1096 M1107 SW393 SW708 I want to change all the M006 to "1", M0114 to "2" and so on. What I am trying is not working. data1$sample[data1$sample =='M006'] <- "1" Warning message: In `[<-.factor`(`*tmp*`, data1$sample ==

Hi Guys I am Abhishek, primarily a bioinformatician. I have recently started using a lot of R thanks to some excellent packages available. Lately I have felt the need to batch process few of the R scripts I have been working with and strangely enough I am not able to find a good resource on how to best do this. I did find few old threads on the archives but none convinced me much. So here I am

Hi All I am wondering if people based on their experience could share what methods one could use to compare two gff/gtf files. The reason why I want to do so is that we have constructed a RNA-Seq based transcriptome and would like to compare it with reference transcriptome we had from in-silico approaches. Ideally we are looking to find out 1. new genes we see 2. transcripts where the

Hi friends, I have following data and would like to plot this with barchart() availble with lattice package. RsID Freqs Genotype AAA 63.636 1/1 AAA 32.727 1/2 AAA 3.636 2/2 BBB 85.965 2/2 BBB 14.035 2/1 CCC 63.158 1/1 CCC 21.053 1/2 CCC 15.789 2/2 DDD 26.786 2/2 DDD 46.429 2/1 DDD 26.786 1/1 EEE 32.759 2/2 EEE 43.103 2/1

Hi All I am looking for a way to prefix a constant value to all the rows in column in a data frame. Eg. V1 2 3 4 5 I want to make it like this V1 number2 number3 number4 number5 Thanks! -Abhi [[alternative HTML version deleted]]

Hi All I am looking for some resource to learn data normalization. I understand I am talking very broad here, I need something like a primer to give me a jump start. If you happen to know any good resource please do let me know. Cheers, -Abhi [[alternative HTML version deleted]]

Hi, I am trying to generate the DFG of machine functions. Initially, I added a pass to generate the DFG of LLVM IR functions. This was based on the mail thread - http://lists.cs.uiuc.edu/pipermail/llvmdev/2009-September/025582.html. This pass worked fine and I was able to generate DFG of LLVM IR functions. Later, I ported the DFG pass code for machine functions. I ported the InstIterator.h

I tried debugging it and the issue seems to be in the implementation of MachineInstrIterator.h and the way it interacts with GraphWriter.h functions. I found this by replacing the ( template <> struct GraphTraits<MCDFGraph<MachineFunction*> >) with a similar MCDFGraph based template of CFG similar to the one in MachineFunction.h (similarly replacing the DOTGraphTraits with the

Hi All, Actually I am working with the OpenSSH version 6.2p which is vulnerable to above mentioned vulnerabilities. So am looking for some help how I can fix these vulnerabilities in my version. I need to fix it in the OpenSSH code. Regards Abhishek

Hi Gert, Thanks for your reply. But we can't upgrade to 7.2 version also we don't have plan to upgrade in near future. Can I fix these vulnerabilities in the current version?
