I'm running XLConnect 0.2-1 that depends on rJava 0.9-3. I am only able to work with 2 workbooks before I get this error... > SppRich = wb["SpeciesRichness"] # This command calls an Excel > spreadsheet Error: OutOfMemoryError (Java): GC overhead limit exceeded I have tried... > rm(list = ls()) ... to clear the workspace, but it doesn't help. I am using RStudio

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.

Hello, thanks for bringing this topic up, and it would be excellent if we could come of with a generic solution for this in base R. It is one of the top frequently asked questions and requested features in parallel processing, but also in sequential processing. We have also seen lots of variants on how to attack the problem of reporting on progress when running in parallel. As the author

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.
