I wrote some code which reads a gzipped text file directly from the web with gzcon(url()) and it works perfectly on OSX, but I cannot get it to work on linux at all, trying several different R versions and linux distributions. Any ideas? Here's an example of my code: z <- gzcon(url("ftp://ftp-private.ncbi.nlm.nih.gov/pubchem/.fetch/8897497837079742771.sdf.gz")) sdf <-

The interpretation of regular expressions with repetition quantifiers in the 'gregexpr' function seems to have changed between R Version 2.2.0 and 2.3.0. The 'gsub' function, however, gives the same results in R Versions 2.2.0 and 2.3.0. Below is an example that demonstrates the version differences of the 'gregexpr' function. I am not sure whether this new behavior is

We've mostly gotten our Asterisk install working, but there are a couple glitches I haven't been able to fix. I'm looking for someone who knows Asterisk, can do some consulting work, and is in Southern California. Los Angeles or Orange County are ok, but I'd prefer someone in the Inland Empire, with strongest preference given to people here in the High Desert or in the San

I need to use a method (called by one of my controllers) without using the layout. All the other methods in the controller need to use this layout except for thismethod (becausae it''s called by an Ajax script). I know how to use :layout=>layout_name when calling a method from another method, but nothing is calling this. The layout needs to be removed in the method itself or I need

Dear list, I am running into 2 problems when using the optimize function from the stats package (note: I've also tried unsuccessfully to use optim, nlm, & nlminb). The second problem is caused by my solution to the first, so I am asking if anyone has a better solution to the first question, or if there exists a solution to the second problem. I should also mention that what I am

Dear List, After running a compound symmetric model using gls, I realized that the default contrasts were not the ones that made the most sense given the biological relationships among the factor levels. When I either changed the factor levels to re-arrange the order they occur in the gls model (not shown below) OR specifically change the contrasts I get the exact same estimates for the

Hi, I am writing a function that includes 'sum' function such as: f<-function(x){ c<-c(-1,0,1) f<-sum(c+x) } expecting f to be -1+x+0+x+1+x=3x. But I found out that f is sum(x). So, f is always a scalar, which means that f(c(0,1)) is not a vector as c(0,3), but 3(0+1)=3. I would like to ask you helping me in solving this problem. I would like to thank you in advance. Sungsu.

Hi All, Does anybody know of any existing functions that will calculate distance inland from a coastline? It's possible to test if a lon,lat location is land or sea using map.where(), but I need to add a buffer to this of say 2km, to allow for points that are just on the coast, and below the resolution of the worldHires database. I'm working with a marine mammal satellite telemetry

I'm trying to connect a sip call from sipgate to Asterisk A to Asterisk B. Both are behind NAT, but port forwarded. I get the connection, but no voice - either in or out. I can call on SIP from A to B (and from B to A). Do it all the time. Asterisk A receives SIP calls from Junction and Teliax. CLI on A looks right: == Using SIP RTP TOS bits 184 == Using SIP RTP CoS mark 5 ==

Hello. I'm looking for a fast way to group by similarity many (5-10k) long (2-10k points) time series. Using PAM on distance matrix obtained via as.dist(1-abs(cor(data))) produces usable results but it's rather slow and doesn't catch slightly shifted time series. DTW implementation from package 'dtw' is orders of magnitude slower even with global window constraints which

I have a question regarding accessing the names of list components when applying a function with lapply. Here is an example that demonstrates what I'd like to do. I have a list like this one: mylist <- list(a=letters[1:10], b=letters[10:1], c=letters[1:3]) Now I would like to append the names of the list components to their corresponding vectors with the c() function. I thought this

Hello,Everybody, Now I am using R (D)COM Server from Python to manipulate some data. When I try to use "read.table" function to read some data, an error occurred. However these statements work well when they are input to R directly. It is so odd. The Python scripts are as the following, from win32com.client import Dispatch sc=Dispatch("StatConnectorSrv.StatConnector")

Dear R Help, I believe the glmer() function in lme4 automatically fits an unstrucruted covariance matirx for the random effects. Is that true? If so, do I have an option to somehow ask for a diagonal structured covariance matrix?
