two plots. Base R only.

Goal

Run every block and confirm the chart is visible.

par(mfrow = c(1, 2))
barplot(c(21, 15, 15), names.arg = c("Nai", "Mom", "Kis"), main = "Units")
plot(1:4, c(48, 55, 92, 150), type = "b", main = "Rain")
par(mfrow = c(1, 1))
print("par")

barplot(c(21, 15, 15, 18, 12), names.arg = c("Nairobi", "Mombasa", "Kisumu", "Nakuru", "Eldoret"), col = "#0f6b52", main = "Units")
print("barplot")
