In the example below, how can I round the x label to even numbers? I cant convert them as factors first, because then geom_smooth
does not work
library(ggplot2)
set.seed(32)
df <- data.frame(a = as.integer(rnorm(250, 2, 0.1)))
df$b <- df$a + rnorm(250)
df$id = 1
df_2 <- df
df_2$id <- 2
df_tot <- rbind(df, df_2)
ggplot(df_tot, aes(x = a, y = b)) +
geom_smooth() +
facet_wrap(~id)
If we want even numbers, an option is to add labels
as a function in scale_x_continuous
library(ggplot2)
ggplot(df_tot, aes(x = a, y = b)) +
geom_smooth() +
facet_wrap(~id) +
scale_x_continuous(labels = function(x) seq(2, length.out = length(x)))
