Hi,

You could miss Java requirement on your system. see rJava

For xlsx reading and manipulation know that there is openxlsx and readxl and writexl; All of them does not have the java dependency.

One advice for next time: do not hesitate to provide some context and some friendly introduction too ! :wink:
