Answer 1

If you know exactly where you want your break values to be, then just tell ggplot

plot1<- ggplot(test, aes(yr, y=value)) +
geom_line()+
scale_x_date(breaks = seq(as.Date("2010-01-01"), as.Date("2050-12-31"), by="5 years"), 
    labels=date_format("%Y")) +
scale_y_continuous(breaks=seq(-4,6, by=1))
