R Question

Importing .xlsx file with special characters

I am using the function readWorksheet from the package XLConnect to import Excel sheets in R. These sheets contain special characters (e.g., ø, õ, ú) which R does not handle very well. As far as I know, there is no "encoding" argument for the function readWorksheet as there is for the read.csv one.

Here is what I am doing so far:

data <- readWorksheet(loadWorkbook("data.xlsx"), sheet = 5)

Is there any option I could use to let R know I have special characters?

I am using RStudio 0.99.903 on macOS Sierra 10.12.1.

This is UTF-8 letters table http://www.utf8-chartable.de/

I use package xlsx for excel files:

read.xlsx(file = ".xlsx", sheetName = "Arkusz1", encoding = "UTF-8", stringsAsFactors = F)

This is in polish language, but print and read.xlsx reads all letters like "ś", "ć" etc.

finally if you can't read xlsx, just save your excel as .csv and read csv with encoding
