Hello All, I am trying to read my Eaton 5P 1550 with the Rs-232 port but I cannot get nut to read the driver from my Rs-232 to USB adaptor. When I perform lsusb -t it says my B&B electronics adaptor uses driver ftdi_sio How do I get the nut to read information coming from that??

I need to reformat long data into a wide format (matrix for another program) but it does not seem straight forward. Can not seem to get it to work since some data elements are strings. Anyone have time to look at the issue? Tnx Bruce -- Bruce W. Miller, Ph.D. Conservation Ecologist Neotropical Bat Project office details Gallon Jug, Belize Mailing address P.O.

Hi, I'd like to get mean values for the margins of my casted data.frame. For the casting I am using dcast() from reshape2. However, when I set the margins parameter (margins=c("grand\_row")) I get following error concerning an unrecognized escape character '\_'. So what is the correct command to get the outermost margins only in reshape2? /johannes [[alternative HTML

Hi again all, As the original code lines I had dated back to 2007 that may have predated reshape2? In any case the use of *dcast *rather than /*cast*/ solved the issue. Then with 3 steps: Stop read Think I saw I just needed to change the line input.cast <- cast(input.melt, Species ~ *Date*, fun.aggregate = sum) to input.cast <- cast(input.melt, Species ~ *Time*, fun.aggregate = sum)

I am not really sure what the warning means but I think your underlying problem is that all your variables are factors. Did you intend the values in each variable to be character? data.frame':??? 3 obs. of? 5 variables: ?$ V1: Factor w/ 3 levels "Name1","Name2",..: 1 2 3 ?$ V2: Factor w/ 3 levels "nam1","name-1",..: 1 3 2 ?$ V3: Factor w/ 3 levels

Reshape2 is a reboot of the reshape package. It's been over five years since the first release of the package, and in that time I've learned a tremendous amount about R programming, and how to work with data in R. Reshape2 uses that knowledge to make a new package for reshaping data that is much more focussed and much much faster. This version improves speed at the cost of functionality,

Running 2.15.0 on Slackware-13.1 with all packages in /usr/lib/R/library. Package reshape2 is in the library but there are no vignettes seen by R. If this is the result of something I did incorrectly, please point out how to install the vignettes with the package. I can get help for melt and cast but no reference on how to access the vignettes. Pointer appreciated, Rich

Dear R users, In order to install reshape2 package, I gave the following command: install.packages("reshape2",dep=TRUE) However, it is not getting installed. The message that I am getting is: Warning: dependencies ‘plyr’, ‘stringr’, ‘testthat’ are not available trying URL ' http://ftp.ctex.org/mirrors/CRAN/src/contrib/reshape2_1.2.2.tar.gz' Content type

Hello--I'm doing a simple crosstab using dcast: rawfreq <- dcast(nh11brfs, race3~CHCCOPD, length) with the results race3 Yes No NA 1 White non-Hispanic 446 5473 21 2 Other non-Hispanic 29 211 0 3 Hispanic 6 81 1 4 <NA> 10 83 1 How would I modify this call to exclude all missing values; that is, to obtain race3

Dear help list: I am trying to reshape a data frame from long to wide format and with a reduced variable list using reshape2. The original data frame format is: Site Obs_no LengthSite 1 Obs 1 10Site 1 Obs 2 13Site 1 Obs 3 14.........Site 2 Obs 1 5Site 2 Obs 2 7Site 2 Obs 3 9 Site and Obs_no are factors and Length is a numeric variable. There are 15

I seem to be running into the same problem reported in https://stat.ethz.ch/pipermail/r-help/2010-November/258265.html I cannot seem to transform a dataset from long to wide using reshape2. Clearly I am missing something very simple but a look at the manual and the reshape paper in JSS does not suggest anything. Any advice would be welcome ===========================load

Te agradezco mucho Javier por tu mensaje, sobre el tema de referencia, solamente que al poner la instrucción library dataset, el sistema responde Error in library(dataset) : there is no package called ‘dataset’. Lo anterior sucede tanto con R 3.0.3 como con R 3.1.0 pero además al entrar a los directorios, encuentro que en los dos casos sí existen las carpetas library y dentro de éstas también

I've successfully reformatted data frames from long to wide with reshape2, but this time I'm getting errors that I want to understand and resolve. Here's the data frame structure and the results of the melt() and dcast() functions: str(waterchem) 'data.frame': 128412 obs. of 8 variables: $ site : Factor w/ 64 levels "D-1","D-2","D-3",..: 1 1
