...te any inputs on the best statistcal approach to tackle this problem. I am thinking that we can find correlation coefficients between A and C, and between B and C, but I am not sure this answers the question. Also we do not know whether the correlation between them is linear or non linear. Thanks Lalitha

...the same using barplot2. However I also need similar information in a tabular form using percentages. i.e in each age bin, what is the PERCENTAGE of IDs with a member_flag of 'Y' I am trying to work with table for the same, but would appreciate some guidance regarding the above. Thanks Lalitha

...fore plotting a x-y plot, i wish to compute average clock-rate in each of the bins for the age and then plot a x-y plot of the age v/s clock rate. Can anyone point me to appropriate functions for the same? I am trying to work with prop.table, cut, break, etc. But I am not heading anywhere. Thanks Lalitha

...just one tree and need a function to return distances between various pairs of nodes on the tree. Is there any other package out there that has this functionality? Thanks for your responses to my earlier queries. As a beginning R programmer, your responses have been of utmost help and guidance.

This function does some post processing on the coefficients returned by coef(fit), puts them in a list and sends it to another function. (i.e. around 6 lines of code after the call to fit).

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

..., despite discussing complex libraries, techniques etc, dont always seem to provide such handy hints/tips and tricks for manipulating data, which is a first stumbling block for newbies like me. I would greatly appreciate if you could point me to such resources as well, for future reference.

...dows to access the database without encountering any such problem I even tried setting up the "mysqldsn" DSN as a system DSN instead of a user DSN. I would like to know a) whether this is a permissions issue at some level b) whether there is any solution for this problem in R Thanks Lalitha

Hi I am new to Cygwin and Linux. I installed R under Cygwin as part of the setup I chose "All" during installation, for all packages. So I have the FULL installlation of cygwin up and running, including gfortran. *Under Cygwin, how do I check and configure the path to the various libraries?* I am trying below command and it says, cannot find "lgfortran" But I have installed
