Woring message in as.yearmon()
I can't reproduce that. When I run it I get no warning. Check your versions:
Lines <- "1946 4 1.27
+ 1946 5 1.27 + 1946 6 1.27 + 1946 7 1.27 + 1946 8 1.52 + 1946 9 1.52 + 1946 10 1.52 + 1946 11 1.52 + 1946 12 1.62 + 1947 1 1.62 + 1947 2 1.62 + 1947 3 1.62 + 1947 4 1.87 + 1947 5 1.87 + 1947 6 1.87"
res <- read.table(textConnection(Lines)) library(zoo)
Warning message: closing unused connection 3 (Lines)
as.yearmon(paste(res[, 1], res[, 2], sep = "-"))
