ggplot warnings - Removed xx rows containing missing values (geom

I have below ggplot

library(ggplot2)
library(quantmod)
dat = data.frame(x = as.yearqtr(seq(as.Date('2002-01-01'), length.out = 17, by = '95 day')),
                    y2 = c(19747, 19343, 19007, 18336, 17534, 16548, 15536, 14400, 13428, 12686, 11877, 11250, 10625, 10122, 9740, 9314, 8892))

ggplot(dat, aes(x = x))  
  geom_col(aes(y = y2), fill = 'red')  
  scale_x_yearqtr(limits = c(dat$x[1], dat$x[17]))

While this is working fine, I am getting below warning

Warning message:
Removed 2 rows containing missing values (geom_col).

So basically, ggplot is removing first and last observations. Is there any way to retain them forcefully while keeping the present layout?

CodePudding user response：

You can remove scale_x_yearqtr(limits = c(dat$x[1], dat$x[17])) to make it work.

If you wish to keep the scale_x function, then one of the very low-level solution is to play around with your limits argument. Just add a little bit of padding to the limits to expand it.

library(ggplot2)

ggplot(dat, aes(x = x))  
  geom_col(aes(y = y2), fill = 'red')  
  scale_x_yearqtr(limits = c(dat$x[1] - 0.1, dat$x[17]   0.4))
