I am working through Rob Hyndman's FPP3. I am on section 2.5 and there is an example about Australian holiday tourism. Here is the example with output:
holidays <- tourism %>%
filter(Purpose == "Holiday") %>%
group_by(State) %>%
summarise(Trips = sum(Trips))
holidays
#> # A tsibble: 640 x 3 [1Q]
#> # Key: State [8]
#> State Quarter Trips
#> <chr> <qtr> <dbl>
#> 1 ACT 1998 Q1 196.
#> 2 ACT 1998 Q2 127.
#> 3 ACT 1998 Q3 111.
#> 4 ACT 1998 Q4 170.
#> 5 ACT 1999 Q1 108.
#> 6 ACT 1999 Q2 125.
#> 7 ACT 1999 Q3 178.
#> 8 ACT 1999 Q4 218.
#> 9 ACT 2000 Q1 158.
#> 10 ACT 2000 Q2 155.
#> # … with 630 more rows
However, when I use the same code I get the following output:
> holidays
# A tibble: 8 x 2
State Trips
<chr> <dbl>
1 ACT 12089.
2 New South Wales 238741.
3 Northern Territory 14917.
4 Queensland 170787.
5 South Australia 52887.
6 Tasmania 31229.
7 Victoria 179228.
8 Western Australia 63349.
As you can see, the tsibble has been changed to a tibble. When I run everything but the summarise function, I still get a tsibble. I am thinking that perhaps the summarise function is somehow changing the type to tibble. Any help would be appreciated. Thanks!
I uninstalled and reinstalled the tsibble package. I noticed that my original version was 0.8.6 but after installation I now have 0.9.0. After I did that it fixed the issue. Thanks!
