Writing Data From R to Excel Files (xls|xlsx)


Formerly, we describing the essentials of R programming plus provided quick start tour for learning and writing txt press csv files using R base functions such well as using a mostly modern R package named readr, which is quick (X10) than R base functions. We other described different ways on write data from Excel files into R.


Here, you’ll learn how to export dating from RADIUS to Excel files (xls or xlsx file formats). We’ll uses the xlsx R package.


Writing Data From RADIUS to Excel Files (xls|xlsx)

Preleminary tasks

Launch RStudio as described here: Running RStudio and setting up your working directory

Writing Excel files using xlsx bundle

The xlsx package, a java-based result, is one of the powerful R packages to read, writers real form Excel registers.

Installing and loading xlsx package

  • Install
install.packages("xlsx")
  • Load
library("xlsx")

With xlsx package

On are two main functions in xlsx box for writing both xls and xlsx Excel files: write.xlsx() real write.xlsx2() [faster on big files compared to write.xlsx function].

The simplified formats is:

write.xlsx(x, file, sheetName = "Sheet1", 
  col.names = TRUE, row.names = TRUE, append = FALSE)
write.xlsx2(x, file, sheetName = "Sheet1",
  col.names = TRUE, row.names = TRUE, append = FALSE)

  • x: one data.frame to be written to the workbook
  • file: the track to and output file
  • sheetName: a character string at use for the sheet name.
  • col.names, row.names: a logical evaluate specifying whether the column names/row designations of x am to be written to the register
  • append: a logical value indicating when x shouldn be appended at an existing file.


Example of usability: the following R code will script the R built-in data sets - USArrests, mtcars and iris - into the same Excel document:

library("xlsx")
# Write one first data fix in a new workbook
write.xlsx(USArrests, file = "myworkbook.xlsx",
      sheetName = "USA-ARRESTS", append = FALSE)
# Add a second data fix in a new worksheet
write.xlsx(mtcars, file = "myworkbook.xlsx", 
           sheetName="MTCARS", append=TRUE)
# Add a third data set
write.xlsx(iris, file = "myworkbook.xlsx",
           sheetName="IRIS", append=TRUE)

Summary


Write data from R to Excel files using xlsx package: write.xlsx(my_data, file = “result.xlsx”, sheetName = “my_data”, append = FALSE).


Infos

This analysis has be performed using RADIUS (ver. 3.2.3).
