The following example illustrates the use of XLConnect to produce a simple report:
require(XLConnect)# Create new Excel workbookwb<-loadWorkbook("earthquakes.xlsx",create=TRUE)# Create worksheet to hold datatargetSheet<-"Earthquakes"createSheet(wb,name=targetSheet)# Export earthquake datawriteWorksheet(wb,data=quakes,sheet=targetSheet)# Create cell style to color events with a magnitude >= 6.0 on the# Richter scalelargeMagnitudeStyle<-getOrCreateCellStyle(wb,name="Large Magnitude")# Use solid red foreground to color rowssetFillForegroundColor(largeMagnitudeStyle,color=XLC$COLOR.RED)setFillPattern(largeMagnitudeStyle,fill=XLC$FILL.SOLID_FOREGROUND)# Determine large magnitude earthquakesrowIdx<-which(quakes$mag>=6.0)# 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(quakes)),col=rep_len(seq_len(ncol(quakes)),length(rowIdx)),cellstyle=largeMagnitudeStyle)# 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).
