Please try to exemplify your request a little better, what kind of information you want to store, what would be the class of the object, a vector, a list, a dataframe?
I agree with FJCC, it seems like a dataframe could be a good option, for example.
data.frame(stringsAsFactors = FALSE,
quarter = c("Q1", "Q2"),
from = as.Date(c("2019-01-01", "2019-04-01")),
to = as.Date(c("2019-03-31", "2019-06-30")),
var1 = c(1, 2),
var2 = c("a", "b")
)
#> quarter from to var1 var2
#> 1 Q1 2019-01-01 2019-03-31 1 a
#> 2 Q2 2019-04-01 2019-06-30 2 b
