如何从 kableExtra kbl 表中删除 NA？

Question

When I run this code:

library(kableExtra)

table %>%
  kbl(caption ="Table 3: Data for Difference Equation Estimation.",col.names = c("Location",
                           "Year",
                           "Price",
                           "Per Capita Quantity",
                           "$\\Delta{P}$",
                           "$\\Delta{Q}$")) %>%
  kable_styling(full_width = F, position = "left")

I get the following:

How can I remove the NAs?

Answer 1

knitr::kable() is the foundation of kableExtra::kbl() . If you look at the help documentation for knitr::kable() it says:

Missing values (NA) in the table are displayed as NA by default. If you want to display them with other characters, you can set the option knitr.kable.NA, eg options(knitr.kable.NA = '') to hide NA values.

Therefore you might try:

options(knitr.kable.NA = '')

table %>%
  kbl(caption = "Table 3: Data for Difference Equation Estimation.",
      col.names = c("Location",
                    "Year",
                    "Price",
                    "Per Capita Quantity",
                    "$\\Delta{P}$",
                    "$\\Delta{Q}$")) %>%
  kable_styling(full_width = F, 
                position = "left")
