The goal of dagtex is to to create tikz DAGs from R. Under very early development and a bit of neglect.
You can install the development version of dagtex from GitHub with:
# install.packages("remotes")
remotes::install_github("malcolmbarrett/dagtex")This is a basic example which shows you how to solve a common problem:
library(dagtex)
dagtex() %>%
add_node("x") %>%
add_node("y") %>%
add_edge("x", "y", is_curved = TRUE)dagtex() %>%
add_node("u1") %>%
add_node("l") %>%
add_node("a") %>%
add_node("y") %>%
add_node("u2", below = "u1") %>%
add_node("u3", below = "l") %>%
add_edge("u1", "l") %>%
add_edge("l", "a") %>%
add_edge("u1", "y", is_curved = TRUE, annotate = annotate_edge("wow")) %>%
add_edge("l", "y", is_curved = TRUE) %>%
add_edge("u2", "l", start_position = "north", end_position = "south") %>%
add_edge("u2", "a", start_position = "north", end_position = "south") %>%
add_edge("u3", "a", start_position = "north", end_position = "south") %>%
add_edge("u3", "y", start_position = "north", end_position = "south")
