Use arrow to represent the big/small value for better visualization

[ShixiangWang]

To fix #16, I read the source code and did some modification. I think it is better than the previous limits option.

devtools::install_github("ShixiangWang/forestmodel")

library(forestmodel)
library("survival")
library("dplyr")
pretty_lung <- lung %>%
  transmute(time,
            status,
            Age = age,
            Sex = factor(sex, labels = c("Male", "Female")),
            ECOG = factor(lung$ph.ecog),
            `Meal Cal` = meal.cal
  )

print(forest_model(coxph(Surv(time, status) ~ ., pretty_lung)))
# Use arrow to represent the big/small value
print(forest_model(coxph(Surv(time, status) ~ ., pretty_lung), 
                   limits = c(log(0.3), log(15))))

Best,
Shixiang

Thanks for accepting :). I added a site for this package, it will show info like https://shixiangwang.github.io/forestmodel/, you can set this in this repository setting, it will render https://niknakk.github.io/forestmodel/ automatically. I think this the best tool to create a forest plot I found, more examples and a vignette will help more R users know and use it. If you have spare time, you could try to add them.

Best,
Shixiang

Thanks @ShixiangWang for your hard work! I've not used pkgdown before, but will add to the repository (and upload to CRAN) when I have time. I agree that a vignette would be good.
