Query about extracting subsets from a table
Hi I am trying to process tabular data as follows: Data in the input file is of the form genome1 genome2 tree-dist log10escore Genome1 and genome2 are alphabetic. Tree-dist and log10escore are numeric. I wish to extract only those rows from this table where the log10escore is less than -3. data <-read.table(filename); data$log10escore = data$log10escore[ data$log10escore < -3]; I

Packages in R for least median squares regression and computing outliers (thompson tau technique etc.)
Hi I am looking for suitable packages in R that do regression analyses using least median squares method (or better). Additionally, I am also looking for packages that implement algorithms/methods for detecting outliers that can be discarded before doing the regression analyses. Although some websites refer to "lms" method under package "lps" in R, I am unable to find such a

Query about using table
Hi I have data of the following form ID age member_FLAG 1 25 Y 2 36.75 N 3 75.5 N ......... ......... I want to get a histogram of this data showing distribution of member_flag in each age-bin i.e. how many values in each age bin have a member_flag of 'Y' and how many have 'N'. I was able to do the same using barplot2. However I also need similar

Query about data manipulation
Hi Thanks much for the prompt response to my earlier enquiry on packages for regression analyses. Along the same topic(?), I have another question about which I could use some input. I am retreiving data from a MySQL database using RODBC. The table has many BLOB columns and each BLOB column has data in the format "id1 \t id2 \t measure \n id3 \t id4 \t measure...."

Query about using optimizers in R without causing program to crash
Hi I am a newbie to R and am using the lm function to fit my data. This optimization is to be performed for around 45000 files not all of which lend themselves to optimization. Some of these will and do crash. However, How do I ensure that the program simply goes to the next file in line without exiting the code with the error "Error in lm.fit(x, y, offset = offset, singular.ok =

Query about finding correlations
Hi I have a dataframe which has 3 columns of numeric data A,B,C each of which has been obtained independent of the other. We are trying to find out, which of A or B cause C i.e. We are hypothesising that C is the effect and either A or B, not both is the cause. i.e. A causes C and this cause-effect relationship explains B. The data for A contains more noise than that for B. We are working with
