This R package simplifies the creation of .xlsx files by providing a high level interface to writing, styling and editing worksheets. Through the use of Rcpp, read/write times are comparable to the xlsx and XLConnect packages with the added benefit of removing the dependency on Java.

Current stable version is available on CRAN via

install.packages("openxlsx", dependencies = TRUE)

install.packages(c("Rcpp", "devtools"), dependencies = TRUE)
require(devtools)
install_github("ycphs/openxlsx")

Please let me know which version of openxlsx you are using when posting bug reports.
