XLConnect 1.0.1 now available from CRAN and from our GitHub repository. 
We are pleased to announce the release of XLConnect 1.0.1. This release is mainly a maintenance release and comes with the following changes:
- Upgrade to Apache POI 4.1
- Adapt Java implementation to make use of Java 8 and remove some dependencies
- Remove dependency on XLConnectJars, download required jars at installation time
The following example illustrates the use of XLConnect to produce a simple report:
require(XLConnect)# Create new Excel workbookwb<-loadWorkbook("cities.xlsx",create=TRUE)# Create worksheet to hold datatargetSheet<-"Cities"createSheet(wb,name=targetSheet)# Export city datawriteWorksheet(wb,data=boot::bigcity,sheet=targetSheet)# Create cell style to color events with a magnitude >= 6.0 on the# Richter scalehighGrowthStyle<-getOrCreateCellStyle(wb,name="High Growth")# Use solid red foreground to color rowssetFillForegroundColor(highGrowthStyle,color=XLC$COLOR.GREEN)setFillPattern(highGrowthStyle,fill=XLC$FILL.SOLID_FOREGROUND)# Determine high growth citiesgrowth<-boot::bigcity$x/boot::bigcity$u# value is for upper quartilerowIdx<-which(growth>=1.4410)# Color rows accordingly# NOTE: Since we include a header row in the worksheet# we need to offset the row indices by 1!setCellStyle(wb,sheet=targetSheet,row=rep(rowIdx+1,each=ncol(boot::bigcity)),col=rep_len(seq_len(ncol(boot::bigcity)),length(rowIdx)),cellstyle=highGrowthStyle)# Save workbooksaveWorkbook(wb)XLConnect is a comprehensive and cross-platform R package for manipulating Microsoft Excel files from within R. It does not require any installation of Microsoft Excel or any other special drivers to be able to read & write Excel files. The only requirement is a recent version of a Java Runtime Environment (JRE).
