I have a simple (!) problem. What I want to do is to create a legend with Greek letters, and substituting numbers into the legend. Like this: mu=1:3 Mean=rep(mu, each=20) plot(runif(60), rnorm(60,Mean,0.1), pch=Mean) # create a plot legend(0.6,1.7, paste("mu =", 1:3), pch=mu) but with a Greek letter mu. I think the solution has something to do with substitute() possibly along with

Does anyone know of example r-code/packages for carrying out analysis? Preferably this would have examples from real experimental data of two or more competing species... Thanks Chris Buddenhagen [[alternative HTML version deleted]]

(Using BRugs 0.7-5, R 2.14.2 32-bit on 64-bit Windows 7, OpenBUGS 3.2.1) 1. BRugs crashes R for me as follows. Sorry about the lack of detail; please let me know if / how to supply a more useful bug report on this issue. fit <- BRugsFit(...) # BRugs and OpenBUGS runs fine, the parameter estimates are reasonable # across 3 chains samplesBgr("beta") # crash

Dear users, I'm trying to get a dot plot but always end up with a boxplot. Can someone please tell me what I am doing wrong? df <- structure(list(FACETTE = structure(c(1L, 1L, 1L, 1L, 2L, 2L, + 2L, 2L), .Label = c("base", "tip"), class = "factor"), Sq = c(274836, + 0.74182, 0.709205, 0.984552, 279869, 255712, 26566, 301464)), .Names = c("FACETTE",

I try to do a test for dirichlet process for Multivariate normal, but Winbugs always says "expected multivariate node", does that mean I miss something at initialization? I will really appreciate the help to solve this problem Here is the R code, and Winbugs code. model { for(i in 1:N){ y[i,1:2] ~ dmnorm(mu[i,],tau[i,,]) S[i] ~ dcat(pi[]) mu[i,1:2] <- mu.star[S[i],]

Hi. I am new here, and I am writing this Winbugs code with BRugs. n=length(bi.bmi) Lagegp=13 Lgen=2 Lrace=5 Lstra=15 Lpsu=2 #model gen x race bi.bmi.model=function(){ # likelihood for (i in 1:n){ bi.bmi[i]~ dbern(p[i]) logit(p[i])<- a0 + a1[agegp[i]]+a2[gen[i]]+a3[race[i]] + a12[agegp[i], gen[i]] + gam[stra[i]]+ u[psu[i],stra[i]] } # constraints for a1, a2, a3, a12 a1[1]<-0.0

That said, I have two issues to ask for help with: 1) how to ignore cert errors with a fromJSON call And 2) why the json data from the example link doesn't convert to a data frame. As seen in the following example library("rjson") result <- fromJSON(file =

Regarding the question: From the linux shell I use the "-k" switch with cURL to ignore cert errors.. is there an equivalent in the R world? I have (sometimes) had success by creating a .curlrc file and putting the necessary curl options in it. When R invokes curl, curl picks up the options.

Hi David, .. I think I've got it :-) Please let me know if you see anything glaringly wrong with this: library(RCurl) zWebObj <- postForm("https://www.semantic-mediawiki.org/w/api.php", "action" = "ask", "query" = "[[Category:City]]|?Capital%20of|?Has%20area", "format" = "json" .opts = list(ssl.verifypeer =

[non-tabular json data] -- ok.. so I think I need to figure out how to make it tabular. Thanks! [curl] -- I was hoping there was a cleaner way to do it.. using R to evoke cURL to get the data as text and then passing it into getJSON seems to be what I need to do. Do you by chance have an simple example of using RCurl to get a response ignoring cert errors? ty -Rich -----Original Message-----

Right. I'm trying to access a server within my organization which has a cert error that I cannot fix. The example link I provided was to a site on the web that does not have the cert error. From the linux shell I use the "-k" switch with cURL to ignore cert errors.. is there an equivalent in the R world? -Rich -----Original Message----- From: David Winsemius [mailto:dwinsemius

Hello All - I am trying to use RJSONIO to read in some JSON files. I was wondering if anyone could please comment on the level of complexity of the files it can be used to read, exports from or directly from NoSQL DBMS like MongoDB and such. Also, i understand that in reading the JSON file RJSONIO will automatically create the necessary structures. However I cannot seem to use to to read the

Thanks for the link.? Somehow the information about how to join the bugzilla site was not available at bugzilla and buried in the CRAN web site instructions on reporting bugs (which pointed me at Bugzilla and not the page you showed me). The example is pretty minimal.? I left the tracing statements (flog.trace()) and the toJSON, fromJSON in as I thought they might provide some context for

Hi, I have a very rudimentary kind of question on using unlist(). I am parsing a bunch of JSON text using rjson package. Some data elements in a dictionary happen to be null which rjson parses correctly. > fromJSON(json_str='{"query":{"A":10, "B":null, "C":"hello"}, "query":{"A":20, "B":null,

I'm trying to implement a connection between two processes using a simple socket mechanism. The messages are rather long object stored as JSON. R is crashing with a segmentation fault when I try to read my test message (which is 5305 bytes long). I first send the length in bytes and then I send the actual message. Here is my R code: library(jsonlite) library(futile.logger)

I?ve been tinkering and discovered that the link I need to read json data from is ?https? and there is a certificate warning that I have to click through from a browser. That might be my issue.

Hi Rich, Take a look at the function fromJSON found in the rjson package. Note that the Usage in the help page: ?fromJSON names the second argument 'file' but if you look at the description the argument can be a URL.
