Halo i'm studying chemistry, today we made an experiment and i have to draw a titration kurve for my mess data. we can do it on a mm paper, or we can also use a programe. people from chemistry recomend "R" last year i studied civil eng. and we used Matlab, as I see, R ist very similar to it, but its got other comands. But i think R would be a good help for some exercises. so my

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Greetings, While I've seen this referred to a lot of places, I haven't yet found a posted solution that works for me. Testing has been done from a Mac running OSX 10.5.8 Here's what I have so far: if anyone can give me a next step to test, I'd appreciate it. If anyone can give me a complete solution, I'd appreciate it even

I think I more or less understand what a ?wrapper? is, but I?d like to hear how more experienced R users define it, and especially I'd like to know if there is a formal definition. In my reading, it seems like there are a fairly wide range of meanings, but they are all conceptually similar. I've looked in a couple of the classic R texts, the extensions and developers' manuals, and R

I'm not sure if I should bother you team with this, apologies in case it's a bother. I'm trying gcc 6.2.1 (from devtoolset-6) with R, everything seems to work just fine, except for mzR. Here is failed build: g++ -m64 -shared -L/usr/lib64/R/lib -Wl,-z,relro -o mzR.so cramp.o ramp_base64.o ramp.o RcppRamp.o RcppRampModule.o rnetCDF.o RcppPwiz.o RcppPwizModule.o RcppIdent.o

I am using autofs to mount user's home and group directories. The setup works fine for home directories which are mounted after user logs in. The group shares are also mounted, but user has to manually do cd or ls command on group shares, e.g.: ls /groups/chemistry will mount chemistry group share. Is there any way to mount group shares automatically? I noticed that after successful login

Gurus: I keep seeing other people?s code that contain ideas like If (x == 2L) X[-1L] X - 1L I have some idea of what?s going on, but where is the use of concepts like ?2L? documented?

I have tried to compile 2.0.4b and 2.0.5a on AIX3.2.5 and it gives a problem when I test it with "smbclient -L bigserver", that was discussed in the archives. I thought it was fixed. It gives:- [1999/07/22 20:57:05, 0] smbd/uid.c:(68) Couldn't set effective uid to 207. Currently set to (real=0,eff=0). Error was Not owner [1999/07/22 20:57:05, 0] smbd/service.c:(463) Can't

Dear all, Does anyone know how to make a line feed automatically based on the width of console window? For example, when you cat() a long character string just like this: cat("Seminar series is an opportunity for students to learn about ongoing researches in the field of mathematics, computer science, physics, chemistry, and some other related programs. Students must complete a seminar

This is not a request for coding help so there is no reproducible code, rather I am trying to figure out if anyone had had a similar experience. My question is related to partitioning the variance in rda (vegan) results for multiple groups of variables. I have a high dimensional dataset with 79 explanatory variables and 9 response variables. Within those 79 explanatory variables there are ~8

I keep finding the Win32\Huer virus in colorspace_1.1-1.zip for R x64 2.14.1 running MS Windows 7. As a result I am not able to use rattle or ChemometricsWithR. I have tried several different mirrors with the same result. Fortunately AVG has caught and quarantined the problem, but the colorspace package is not available. I can use the package on my Linux OS, but, of course, Linux

Hello, Please always cc the list. As for the question, yes, it does. If you want to remove just the ones with exactly 73.1 use the pattern grep("^73\\.1$", etc) Explanation: Beginning of string: ^ End of string: $ Escape special characters: \\ (needed because the period is a special character.)

I do this on a vanilla-clean R installation, simply: > biocLite("mzR") it pulls some deps in which compile fine, only mzR fails. ... meanwhile... I grabbed devtools and comiled github master - still fails. Should I attach build log? One should not send attachments to the list.. I don't suppose?

I have written a function to plot data which will be used for various different chemistries. A simplified version is: plot_data <- function(risk,levels,chem,sd2,measure){ plot(risk, levels,main=paste ("per", sd2, measure, "\n in usual", chem)) } The problem is with the title. This works fine if the variable "chem" is just text, but if it is an expression...

I have a few questions about the new ORC JIT. I saw Lang Hames (hi!) excellent talk at the llvm-dev meeting a few weeks ago. The ORC JIT is undergoing some API changes and I'd like/need to take advantage of them. (1) How do I take ownership of the ObjectFile once the ORC JIT has created it? I'd like to take ownership of object files generated by the ORC JIT so that I can save them to

Hi- I'm wondering if anyone can help me with my code. I'm coming up dry when I try to get a p-value from the following code. If I make a histogram of my resampled distribution, I find the difference between by groups to be significant. I've ranked the data since I have outliers in one of my groups. mange= c(35, 60, 81, 158, 89, 130, 90, 38, 119, 137, 52, 30, 27,

Hi, all, I need to show only values in a barplot from say 4-12. When I do this, values below 4 are not cutoff. I would appreciate any input into how I could cut the bottom part of the bar off. Best wishes, Art Roberts University of Washington Department of Medicinal Chemistry

I'm a PhD student and I'm working with covariance function. I'm interested to know if exist some packages in R to calculate and plot the bidimensional Autocovariance Function. the input matrix is a matrix that describe a spatial location over a 2-D space and I want to use it in the same way I can use a time serie in the 1-D acf. Thanks, Nicola.

mzR is a Bioconductor package, so better to ask on the Bioconductor support forum https://support.bioconductor.org Oh, I see you did, and then the advice is to avoid cross-posting! The missing .o files would have been produced in an earlier compilation step; they likely failed in some way, so you need to provide the complete compilation output. Did you do this on a version of the package
