Dear R-Help,

I have a list of data frame that I import from excel file using read.xlsx
command.

sheets <- openxlsx::getSheetNames("rainfall.xlsx")
test <- lapply(sheets,function(i) read.xlsx("rainfall.xlsx", sheet=i,
startRow=8, cols=1:2))
names(test) <- sprintf("%i", 1986:2015)

And I got a data.frame with 365 rows and two columns contains date and
rainfall data.
There is a value in rainfall data that i want to change as NA (8888)

test[1]$`1986`
