ggplot for a list?

Bick,

When you import the data, can you create the missing groupings? Trying to
do it after the fact is really hard. Once you do that, it's super easy to
compact this with dplyr::bind_rows().

bic_data %>% dplyr::bind_rows()

Group.1 Pr1 Pr2 Prh SE
1 C 65 54 25 25
2 D 75 88 5 75
3 C 81 66 3 8
4 D 4 57 3 9

If you put a group variable in:
bic_data2 <- list(structure(list(super_group = c(1,1), Group.1 =
structure(3:4, .Label = c("A",

"B", "C", "D", "E", "F"), class = "factor"), Pr1 = c(65, 75), Pr2 = c(54,
88), Prh = c(25, 5), SE = c(25, 75 )), row.names = c(NA, -2L), class =
"data.frame"), NULL, structure(list(super_group = c(3,3), Group.1 =
structure(3:4, .Label = c("A",

"B", "C", "D", "E", "F"), class = "factor"), Pr1 = c(81,4), Pr2 = c(66,
57),Prh = c(3,3), SE = c(8, 9)), row.names = c(NA,

-2L), class = "data.frame"))

bic_data2 %>%
bind_rows() %>%
ggplot(., aes(x = Group.1, y = Pr1, fill = Group.1)) +
geom_bar(stat = "identity") +
facet_grid(. ~ super_group)

â Hi,
I want to plot histogram (like the attached one) and I know it can be done
ggplot() + geom_histogram()
However, here I have a list and I am not sure how I do it. If I convert to
dataframe, I will los the order that I want to keep in the graph (1 and
3).
list(structure(list(Group.1 = structure(3:4, .Label = c("A",
"B", "C", "D", "E", "F"), class = "factor"), Pr1 = c(65, 75), Pr2 = c(54,
88), Prh = c(25, 5), SE = c(25, 75 )), row.names = c(NA, -2L), class =
"data.frame"),NULL, structure(list( Group.1 = structure(3:4, .Label =
c("A",
"B", "C", "D", "E", "F"), class = "factor"), Pr1 = c(81,4), Pr2 = c(66,
57),Prh = c(3,3), SE = c(8, 9)), row.names = c(NA,
-2L), class = "data.frame"))
Any help on this?
Thanks
Bick
