根据军官包文档：
索引在幻灯片布局中的类型不唯一时使用
但是，我找不到任何标识占位符的属性确定其索引的信息。
下面，我提供了layout_properties()的示例输出。
master_name name type id ph_label offx offy cx cy
148 master layout body 14 Text Placeholder 4 7.500000 0.9791667 2.500000 0.5000000
150 master layout body 13 Text Placeholder 16 8.333333 1.6458333 1.416667 1.0000000
151 master layout body 12 Text Placeholder 13 1.583333 5.1458333 5.916667 0.4791667
我看到三种可能为每个文本占位符确定正确的索引值。
id中排名。从示例开始，从顶部开始，索引= 3、2、1 ph_label中的数值旁边。索引= 1、3、2 编辑
对于将来的用户，确定正确索引的是行顺序。
奇怪的是，行顺序最初是我的猜测，但是我发现该规则有些例外。这些异常的原因实际上是，即使本地代码与模板文件完全相同，本地计算机上的布局属性输出还是与闪亮服务器上的输出有所不同。现在为什么会这样？...我不知道。
答案 0 :(得分：0)
据我所知，索引是用户提供的幻灯片位置，layout_properties显示了实际的幻灯片布局。我不相信那里有什么与索引位置相对应。
例如：
doc <- read_pptx() %>%
add_slide(layout = "Two Content", master = "Office Theme") %>%
ph_with_text(type = "body", str = "body (index 1) is text") %>%
ph_with_text(type = "body", str = "body (index 2) is also text")
print(doc, target = "C:/Foo/doc_1.pptx") # Since type is not unique, both are body, they get printed as if they are the same, at the same index position on top of each other.
> layout_properties(doc)
master_name name type id ph_label offx offy cx cy
