I'm trying to run a line of code in R with read.xlsx taken from xlsx package. it used to work fine but something has changed but I'm not sure what.
df_sheet <- xlsx::read.xlsx(lane_info, sheetIndex = 1, startRow=5 ,colIndex = 1:8,as.data.frame=TRUE, header=TRUE,stringsAsFactors=FALSE) # read first sheet
the Error is:
> Error in .jcall(cell, "I", "getCellType") : method getCellType with
> signature ()I not found
