Dear R Community, I am trying to optimize a water quality model that I am using. Based on conversations with others more familiar with what I am doing I plan to implement DEOptim to do this. The water quality model is interfaced through a GUI. I have the input file necessary to alter parameters and run the model as a text file. To do the optimization I have figured out the general procedure

I have a number of programs I wrote on Centos 5 (x86_64) and for one of the programs I do ldd programX linux-vdso.so.1 => (0x00007fff2cb86000) libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003528600000) libm.so.6 => /lib64/libm.so.6 (0x0000003527e00000) libxml2.so.2 => /usr/lib64/libxml2.so.2 (0x0000003531400000) libz.so.1 =>

Hi, Thought I'd just forward this here, because I don't have time to look into it right now, and am off skiing next week. I'd guess that we should be checking for username = ``root'' before going off to do password checks, and rejecting it on that basis first. Cheers, Phil. -- Mind-numbingly stupid UK law alert!

I have a situation where my zpool (with two radiz2s) is resilvering and reaches a certain point, then starts over. There no read, write or checksum errors. The disks do have a fair amount of resilvering to do, as I''ve had a variety of disk failures. But at the core of things, there''s enough parity data to avoid data loss, and the zpool is functioning fine, albeit in a

Greetings - I'm battling POSIXct, as per the code below. My input is actually an XL file, but the weird results below correctly model what I am seeing in my program. Before I punt and use lubridate or timeDate, could anyone please help me understand why POSIXct forces my variable back to GMT? I suspect that I'm not properly coding the tzone value, but it does not throw an

I know this topic has been discussed many times... but what the hell makes zpool resilvering so slow? I''m running OpenSolaris 2009.06. I have had a large number of problematic disks due to a bad production batch, leading me to resilver quite a few times, progressively replacing each disk as it dies (and now preemptively removing disks.) My complaint is that resilvering ends up

Greetings – Grateful for any help on this one: In the following demo code, I am trying to get the points in the line to appear over the same x-axis labels as are used by the paired Bars. It appears, however, that R/lattice ignores the x-axis points used by the bars and plots the x points for the line at ½ points. Can you help me tweak this code so that the nth bump in the line

I am reading dates in Excel2007 into R. Here are the functions I used: library(RODBC) channel<-odbcConnectExcel2007("myfile.xlsx") tmp<-sqlFetch(channel,"1",as.is=T) The dates in myfile.xlsx are all in this format: mm/dd/yyyy. But when I read it to R, some columns look like "yyyy-mm-dd 00:00:00", some columns look like "yyyy-mm-dd", and some

I am trying to implement an ANOVA on a pair of quantile regression models in R. The anova.rq() function performs a basic check to see whether the models are nested, but I think this check is failing in my case. I think my models are nested despite the anova.rqlist() function saying otherwise. Here is an example where the GLM ANOVA regards the models as nested, but the quantile regression ANOVA

Greetings - I am working on a piece of code to simulate vehicle times in and out in each of a number of parking spaces. At this stage, my code basically does what it is supposed to do but for the sequential number of each new parking event for a given space (i.e., the index of the loop variable). Instead of passing the index of the loop variable (iter) to the data frame, it passes the value

Hi list, I know that points involving NAs are not plotted in 'matplot', but when I plot them as lines, I still want the lines to connect all the points (i.e. not broken where there are NAs).? Please see the example below.? How can I achieve this in 'matplot'?? If I can't, any good alternatives so I don't have to use 'plot' + 'lines' and loop through all the

I'm a big fan of both Weka and R (quite new at R :) ), and jumped at the chance to use them together. Unfortunately, I'm running into what is probably a dumb error when trying to view info about my model. A Google search turned up 0 hits for the actual error I got (last line), but you all are smarter! My code is below, but basically my data frame (q) is imported via RODBC and has 1586

R community, I would like to know how to extract rows from a data frame (DF) such that each row in the new data frame (D.F) represents the first instance of a unique variable pairing in the original dataframe (ordered first by variable V1 then by variable V2). The unique function does not seem to be able to accomplish this. I imagine there must be a simple solution for this, but I can't

Sorry if that's a vague subject, but this problem is a little weird and I'm just wondering if there are any suggestions out there. We've got a Samba server (3.0.23) running on a CentOS 5.3 server offering up a data share of 7TB on an XFS filesystem. The authentication all happens through a Samba PDC with an LDAP backend all on a different server. The system in question is just a

How to force R to print 2 decimal places in column of a data.frame? I tried to do so: x = inp(format(rounf(inp$Tamanho, 2), nsmall = 2),) where "INP" is data.frame and "Size" is the name of column.

Hi, I need some help with NFSv4 setup/tuning. I have a dedicated nfs server (2 x E5-2620? 8cores/16 threads each, 64GB RAM, 1x10Gb ethernet and 16x 8TB HDD) used by two servers and a small cluster (400 cores). All the servers are running CentOS 7, the cluster is running CentOS6. Time to time on the server I get: ?kernel: NFSD: client xxx.xxx.xxx.xxx testing state ID with incorrect
