Conditional format entire sheet using Openxlsx in R
问题
我有R中的数据，目前是645行94列。但为了可重现的数据，我们只需使用“iris”数据集。
我想将其另存为带有条件格式的Excel文件，其中包含“A”的每个单元格都会被突出显示。我知道我可以像这样做：
wb <- createWorkbook()
addWorksheet(wb, "Data")
writeData(wb, "Data", iris)
conditionalFormatting(wb, "Data", cols = 1:5, rows = 1:151, type = "contains", rule = "A")
saveWorkbook(wb, "iris.xlsx", overwrite = TRUE)
但我的问题是，我必须手动输入：
cols = 1:5, rows = 1:151
但如果我只想要每个单元格呢？也就是说，下次运行脚本时，我的数据可能是650x100，我不想一直更改这个文本。如何使其默认为整个数据集？

I have data in R thats currently 645 rows by 94 columns. But for a reproducible data lets just take the "iris" dataset.
I want to save that out as an excel with conditioning formatting where every cell that contains "A" gets highlighted. I know I can do something like this:
wb <- createWorkbook()
addWorksheet(wb, "Data")
writeData(wb, "Data", iris)
conditionalFormatting(wb, "Data", cols = 1:5, rows = 1:151, type = "contains", rule = "A")
saveWorkbook(wb, "iris.xlsx", overwrite = TRUE)
But my question is, I had to manually write in:
cols = 1:5, rows = 1:151
But what if I just want it to be every cell? I.e. my data thats 645x94 might be 650x100 the next time I run the script, and I dont want to keep changing that text. How can I just make it default to the whole thing?

使用一些基本函数来获取数据的大小。
尝试：
wb <- createWorkbook()
addWorksheet(wb, "Data")
writeData(wb, "Data", iris)
col_num <- ncol(iris)
row_num <- nrow(iris)
conditionalFormatting(wb, "Data", cols = 1:col_num, rows = 1:row_num, type = "contains", rule = "A")
saveWorkbook(wb, "iris.xlsx", overwrite = TRUE)

Use some basic functions to get the size of your data.
Try:
wb <- createWorkbook()
addWorksheet(wb, "Data")
writeData(wb, "Data", iris)
col_num <- ncol(iris)
row_num <- nrow(iris)
conditionalFormatting(wb, "Data", cols = 1:col_num, rows = 1:row_num, type = "contains", rule = "A")
saveWorkbook(wb, "iris.xlsx", overwrite = TRUE)
