How to insert number of rows/columns in spatial plot using ggplot?

[meitei]

Hello,
I found the following code for spatial plot.
The following code shows 16 maps. How can I make it into either 4 rows or columns?

Thank you

library(sf)
library(tmap) 
library(ggplot2)
load(url("https://github.com/mgimond/Spatial/raw/main/Data/Sample1.RData"))
p=ggplot(data = s.sf, aes(fill = Income)) + 
  geom_sf(col = "red") 
p+ facet_grid(.~ NAME)

Use ggplot2::facet_wrap().

p=ggplot(data = s.sf, aes(fill = Income)) + 
  geom_sf(col = "red") 
p+ facet_wrap(.~ NAME, ncol = 4)
