Create a flextable from a small data frame

set.seed(1)

iris %>% 
  relocate("Species") %>% 
  sample_n(10) %>% 
  arrange(Species) -> iris_slice

header_words <- c("Sepal", "Petal")
last_id_col <- "Species"

make_flextable(iris_slice, header_words = header_words, last_id_col = last_id_col) -> myflex

myflex

Species	Sepal	Petal
setosa	4.40	3.20	1.30	0.20
4.30	3.00	1.10	0.10
5.40	3.40	1.70	0.20
4.60	3.40	1.40	0.30
versicolor	5.80	2.70	4.10	1.00
7.00	3.20	4.70	1.40
5.40	3.00	4.50	1.50
6.10	2.80	4.70	1.20
virginica	6.40	2.80	5.60	2.10
7.60	3.00	6.60	2.10

Create a pivot table with flextable

tibble::tibble(my_letters = sample(letters[1:4], 100, T),
       my_numbers = sample(1:4, 100, T)) -> cross_table

cross_table %>% 
  make_pivot_table(my_letters, my_numbers, theme = "tron") -> tron_cross_table

tron_cross_table

cross_table	my_numbers
my_letters	a	6	8	7	5	26% (26)
b	8	8	10	3	29% (29)
c	3	5	8	5	21% (21)
d	6	3	6	9	24% (24)
		23% (23)	24% (24)	31% (31)	22% (22)	100% (100)

iris %>% 
  dplyr::mutate(Species1 = stringr::str_c(Species, " very good")) %>% 
  make_pivot_table(Species1, Species, show_percentages = "none", tbl_nm = "gold table", theme = "zebra_gold") -> tbl 

tbl

gold_table	Species
Species1	setosa very good	50	0	0	33% (50)
versicolor very good	0	50	0	33% (50)
virginica very good	0	0	50	33% (50)
		33% (50)	33% (50)	33% (50)	100% (150)

export tables to powerpoint

myflex %>% 
  export_powerpoint() # a new ppt is created, named after the table

tron_cross_table %>%
  export_powerpoint("myflex.pptx") # append this slide to the previous ppt

Multiple powerpoint slides
