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.
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)
