All Is there a package or library that will, given a nucleotide sequence 1. calculate the extinction coefficient at 260 nm for (Beer-Lambert's law) 2. calculate molecular weight 3. return it's complementary sequence I was able to find several packages that can do similar calculations for an amino acid sequence for proteins but none for nucleic acids. Any pointers, etc. would be

library(sos) (mp <- findFn('{molecular properties}')) ????? ** found 7 matches in 4 packages and opened two web pages in my default browser with (a) the 7 matches and (b) the 4 packages. The first function was something for amino acids, like you suggested.? Two others returned compound and substance information from PubChem. ????? Does this help? ????? Spencer On

Hi! Just started working at a lab and have only minimal experience with R. I was wondering if there was a way to write a code that would intake a data set of chemical compounds (ex: H2O, CH3) and be able to give an output column of the molecular weight? I tried some really basic coding to try to work with a being a matrix of data with the assigned variables. if (A<-'H')

Hi Spencer Thank you for your suggestion. I tried sos -- Is it actually supposed to actually list out the functions along with the packages? This is what I got: found 7 matches Downloaded 7 links in 4 packages. Ignoring template.

Hi All, What is the R function for computing multinomial distribution, e.g. f(2,1,3; 2/9, 1/6, 11/18, 6)? That is, a total of 6 trials, event 1's p1=2/9, x1=2, event 2's p2=1/6, x2=1, and event 3's p3=11/18, x3=3. thanks, Johnny [[alternative HTML version deleted]]

Hello R Folks... I've been looking around the 'net and I see many complex solutions in various languages to this question, but I have a pretty simple need (and I'm not much good at regex). I want to use a chemical formula as a function argument. The formula would be in "Hill order" which is to list C, then H, then all other elements in alphabetical order. My

Greetings, Working on setting up replication and ran into some errors I have questions about and wondering if there's something I need to change. This one is fairly common: Sep 3 12:58:25 molecular dovecot: dsync-server(user at domain.org): Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync (Modseq 100298 no longer in transaction log) These two I ran into

Is there a simple way to decompose the upper triangle of a correlation matrix to a linear list; For example: X Y Z X 1 2 3 Y 2 1 4 Z 3 4 1 so you get a list like: xy 2 XZ 3 YZ 4 I suspect you can do it with a matrix transformation, but that beyond me at present.

Hello R Users, I am interested in using R to generate quantitative structure-activity relationships (QSARs) for small molecules given a set of molecular descriptors (the X's) and biological data (Y's) (usually tab-delimited data files). Has anyone done this using R ? Would you be willing to share your R scripts (or ideas) for doing this with me ? I am particularly interested in
