What is the method to eliminate NA from facet_wrap in ggplot2?

edit

One way to eliminate NA from facet_wrap in ggplot2 is to use the na.omit() function within the data argument of ggplot(). This function removes any rows with NA values in the specified variable, and the resulting plot will not display any NA values:

library(ggplot2)

# create example data frame with NA values
df <- data.frame(x = 1:10, y = c(1:5, rep(NA, 5)), group = rep(c("A", "B"), each = 5))

# remove NA values and create facet_wrap plot
ggplot(na.omit(df), aes(x = x, y = y)) +
  geom_point() +
  facet_wrap(~ group)

This will create a plot with two facets, one for group "A" and one for group "B", and no NA values will be displayed.
