similar to: Rcmdr, RODBC and XLConnect conflict cause R to crash

Hello, If I run the script : "a<-2 ; a<-a+5 ; a" whith the "submit" buton in Rcmdr the result is 12 !!! But if I run the script "a<-2 ; b<-a+5 ; b" there is no problem and the result is 7. I think there is a bug in the function "onSubmit". Thanks, [[alternative HTML version deleted]]

Any ideas of what is happening when I attempt to load XLConnect? I think I installed everything correctly. I posted what I get when I installed rJava as well as when I attempted to load rJava directly. Thanks in advance for any help you can give on this. library(XLConnect) Loading required package: XLConnectJars Loading required package: rJava Error : .onLoad failed in loadNamespace() for

Hola. Tengo una especie de "poltergeist"... a ver si alguien es capaz de echarme un cable.... sucede al usar los paquetes XLConnect (http://cran.r-project.org/web/packages/XLConnect/) y gWidgets (http://cran.r-project.org/web/packages/gWidgets/) simultáneamente en R 2.15.2 (de 32 bits bajo Windows 7) ... con la versión anterior (2.15.1), en las mismas condiciones, no pasa. Caso 1: #

I have spent hours on R in Windows 7. Just installed 2 days ago so the R package should be current. Currently I am using the RGui (64-bit) for Windows. I can not read an Excel file into R from my computer. Have hours on this. Completely crazy!! I have the XLConnect package loaded. I think it is loaded because when I enter: > loadedNamespaces() [1] "base"

Hi, I have two questions on the function "readNamedRegionFromFile" in XLConnect pacakge. 1. In the documentation, # multiregion xlsx file from demoFiles subfolder of package XLConnect demoExcelFile <- system.file("demoFiles/multiregion.xlsx", package = "XLConnect") # Load a single named region into a single data.frame. df

Hi Everybody In R, the XLConnect package can read and write named region to and from Excel. In order to read a named region with the readNamedRegion function you need to know it's name. You can check is a name exists with existsName, but you still have to know the name. Is there a way to actually get a list of the named regions in XLConnect sinilar to getRanges in the xlsx package. On that

When using XLConnect's readWorksheet, instead of it correctly reading string and numeric columns, I receive NA's with the following message: " Error when trying to evaluate cell A2 - not implemented yet" I do not know what this means. Can anyone please assist? -- __________________________ *Barry E. King, Ph.D.* Chief Modeler Qualex Consulting Services, Inc.

Hi, I tried to read xlsx files by "XLConnect" packages, but the dates are one day earlier than it is supposed to be. I moved from California to Taiwan (Eastern Asia), and it worked well in California, but not in Taiwan. Even if I adjust my Mac time to California time zone, it gives the wrong dates. I don't know which part of the setting (in RStudio or in my Mac?) I should adjust.

Dear R Discussion List, I would like to save my data as a xlsx file. But at first I need to split it and then save each series into a Excel column. Please take a look at the following code: dados <- data.frame(matrix(c("2012-01-01","2012-02-01", "2012-03-01","2012-04-01","2012-05-01","2012-06-01",

Thanks very much for your answer. I?m trying the function ?strtoi? but it fails to convert character to numeric after the command "set[index] <- strtoi(set[index])". > strtoi(set[index]) ## This works: all values are numeric !!! [1] 1 2 3 4 2 8 9 7 > set[index] <- strtoi(set[index]) > print(set[10,1]) ## Problem: must be numeric !!!! [1] "1" Thanks
