yticks.by only works without NAs

[j3ypi]

The yticks.by argument of ggpar() only works without NAs. There is an easy fix for this, since the error message says

Error in seq.default(0, max(y), by = yticks.by) : 
  'to' must be a finite number

max(y) needs to be changed to max(y, na.rm = T) and the problem is solved.

Here's a reproducable example

library(tidyverse)
library(ggpubr)

df1 <- tibble(
  sum1 = c(NA, round(runif(49, 0, 10), 0)),
  condition = rep(c("A", "B"), each = 25)
)

a <- ggbarplot(df1, 
           x = "condition",
           y = "sum1",
           add = "mean_se", 
           ylim = c(0, 10))

ggpar(a, 
  yticks.by = 2)

Unfortunatly I don't have much time at the moment. I will probably get to fix this and issue #71 in september, but until then just write

ggbarplot(na.omit(df1), 
           x = "condition",
           y = "sum1",
           add = "mean_se", 
           ylim = c(0, 10))

instead. Maybe someone else has time to fix it in the meantime.
