Hello, I am working with a database system from which I can retrieve these kinds of user defined fields formed as XML ... <udf:field unit="uM" type="Numeric" name="facs.Stain final concentration">5</udf:field> You can see in the above example that "field" is defined in the namespace "udf", but that the "udf" namespace is

Question 1: I have a long list of variable names such as first <- c("one","two","three") and what I want to do is create a list of lists ... where the names of each of overall lists components are "one","two", and "three". This is the same result as second <- list(one=list(),two=list(),three=list()) Is there a way to exploit

Hi I need to know how to make pch symbols like pch=3 (+) or pch=4(x) or even the border of squares or triangles thicker without changing the size. I have a lot of symbols of different colors but you can't see the colors clearly and I don't want to change the symbol.

What is wrong with the following? x <- 1:2 if(x[1] > 0) { if(x[2] > 0) { print("1 & 2 > 0") } else { print("1 > 0") } } else { if(x[2] > 0) {

Dear R Community, I recently switched to a Mac (10.6.5), and have installed Textwrangler to run code to R. However, I can't install the syntax highlighting file because I can't find the directory: "~Users/username/Library/Application Support/TextWrangler/Language Modules/". Is there a different location I can place the syntax highlighting file? Scott [[alternative HTML

I need to construct a custom XML reader, the files I'm working with are in funky XML format: <str name="author">Paul H</str> <str name="country">USA</str> <date name="created_date">2010-02-16</date> I want to read the file so it looks like: author = Paul H country = USA created_date=2010-02-16 Does any one know how to

Hi, is there a function or an easy way to convert a variable with continuous values into a categorial variable (with x levels)? here is what I mean: I want to transform x: x <- c(3.2, 1.5, 6.8, 6.9, 8.5, 9.6, 1.1, 0.6) into a 'categorial'-variable with four levels so that I get: [1] 2 2 3 3 4 4 1 1 so each element is converted into its rank- value / categorial-value (in

Wanting a commandline solution (for a problem detailed @ http://mailman.unidata.ucar.edu/mailing_lists/archives/netcdfgroup/2012/msg00279.html ) I turned to Rscript, and whacked out the q'n'd https://github.com/TomRoche/GEIA_to_netCDF/blob/master/netCDF.stats.to.stdout.r However it wasn't as quick as hoped, because I spent quite a bit of time figuring out how to pass the arguments.

i want to plot values with frequency on a logarithmic x axis. similar to this example that i found in the web: http://www.usspeaker.com/jensen%20p15n-graph.gif I would like to convert long numbers to si prefix notation like in the example (200000 to 200k, 35000000 to 3.5 M) Of course i could create labels by hand, but i have many files so i need some automatic function. Has anyone done that

Big thanks. newXMLNode works great. Wonder why it is not included in the documentation. There is newXMLDoc and newXMLNamespace, but no mention of newXMLNode.

Just to clarify and hopefully catch the attention of the maintainer: The newXMLNode function is not mentioned in: https://cran.r-project.org/web/packages/XML/XML.pdf which supposedly describes all functions in the package.

Hi, It's a reasonable question. The answer is that it actually is included, but there are many instances across packages where multiple functions are documented on a single help page. The following brings up such a page... (for XML_3.98-1.9) > library(XML) > ?newXMLNode You can see the same on line... https://www.rdocumentation.org/packages/XML/versions/3.98-1.9/topics/newXMLDoc

Hello, I'm attempting to read information from an XML into a data frame in R using the "XML" package. I am unable to get the data into a data frame as I would like.

Thanks to all that replied. I had just looked through the httr code and sure enough for a .csv mime time it calls readr::read_csv(). The httr::content docs suggest not using automatic parsing in a package, rather to determine mime type and parse yourself and Ben's suggestion also works if I do: junk <- readr::read_csv(r1$content, col_types = cols()) Perfect. Using httr rather than

Indeed, Ben, but the question was something more like it is not a Dependency, just Suggested, so why the error... John: If you read the Introduction to the 'raster' package vignette, it indicates that some input formats are supported within the raster package and some rely on other packages. Clearly the attempt to read a TIFF was an example of the latter. Had you used a different input

Hi, If you are using roxygen-style function documentation then why not use devtools::document()?
