Converting a data frame to xts

Question

I\'m trying to convert a data frame to xts object using the as.xts()-method. Here is my input dataframe q:

q
                      t x  
1  2006-01-01 00:00:         


        

Answer 1

I defined an index with the length equal to the number of rows of my tibble. Only after defining the time sequence separately as shown with the example:

ti= seq(from = ymd_hm("2000-01-01 00:00"),
to = ymd_hm("2000-01-02 01:00"), by =  "30 min", tz = "UTC")

tbl <- tibble(t =ti,
    x = 1:length(t))
)

This code worked:

xts.tbl <- xts(tbl[,-1], order.by = ti)

However all data transformed into characters.
