[英]Add slides based on slide position numbers using officer package
我正在使用 Office 创建一个 Power Point 演示文稿。 假设我使用基于blank.pptx
的 for 循环创建了 10 页幻灯片(名为10_slides_ppt.pptx
)。
我的问题是,有没有一种方法可以在 position 编号为c(3, 6, 9)
的幻灯片之前添加一张幻灯片?
最终的ppt会是这样的:
1, 2, (新幻灯片 1), 3, 4, 5, (新幻灯片 2), 6, 7, 8, (新幻灯片 3), 9, 10
代码:
library(officer)
current_pres <- read_pptx('10_slides_ppt.pptx')
# To add new slide 1, but I don't know how to set position of slide
final_pres <- add_slide(current_pres, layout = "Title and Content", master = "Office Theme") %>%
ph_with(current_pres, value = "heading", location = ph_location_type(type = "title")) %>%
add_slide(current_pres, layout = "Title and Content", master = "Office Theme") %>%
ph_with(current_pres, value = "heading", location = ph_location_type(type = "title")) %>%
add_slide(current_pres, layout = "Title and Content", master = "Office Theme") %>%
ph_with(current_pres, value = "heading", location = ph_location_type(type = "title"))
一个选项是move_slide
,它允许像这样移动幻灯片。 由于在 pptx 的末尾添加了一张新幻灯片,我将轻微的从末尾( index = length(.)
)移动到所需的 position。
注意:随着索引在添加和移动幻灯片时发生变化,我添加并反向移动幻灯片,即从 9 到 3:
library(officer)
library(magrittr)
# Make example pptx
current_pres <- read_pptx()
for (i in seq(10)) {
current_pres<- add_slide(current_pres, layout = "Two Content", master = "Office Theme")
}
# To add new slide 1, but I don't know how to set position of slide
final_pres <- add_slide(current_pres, layout = "Title and Content", master = "Office Theme") %>%
ph_with(value = "heading", location = ph_location_type(type = "title")) %>%
move_slide(index = length(.), to = 9) %>%
add_slide(layout = "Title and Content", master = "Office Theme") %>%
ph_with(value = "heading", location = ph_location_type(type = "title")) %>%
move_slide(index = length(.), to = 6) %>%
add_slide(layout = "Title and Content", master = "Office Theme") %>%
ph_with(value = "heading", location = ph_location_type(type = "title")) %>%
move_slide(index = length(.), to = 3)
fn <- tempfile(fileext = ".pptx")
print(final_pres, fn)
