The XLConnect vignette package is a collection of documents that provide additional information about the XLConnect package. It does not provide any functions for manipulating Excel files.

The write.xlsx function is a function in the XLConnect package that can be used to write data to an Excel file. It takes a number of arguments, which can be used to specify the file name, the sheet name, the data to be written, and other options.

“`
library(XLConnect)

Create a data frame

df <- data.frame(x = 1:10, y = 2:11)

Write the data frame to an Excel file

write.xlsx(df, “data.xlsx”)
“`

This code will create an Excel file called data.xlsx that contains the data frame df.
