Save graphs (facet) on multiple pages

Time:09-22

I need to represent an important number of graphs. To do that I used a the facet_wrap_paginate function, but I only have the second page printed/plotted.

Here is a sample of my data:

df <- structure(list(oxygen = c(60.86414, 62.50372, 89.76055, 61.15914, 
61.49936, 61.90402, 61.60323, 61.2873, 75.12329, 60.83503, 63.03796,

    1:20, 21:40, 41:60, 61:80, 81:100, 101:120, 121:140), ptype = integer(0), class = c("vctrs_list_of",

"tbl", "data.frame"), .drop = TRUE), class = c("grouped_df", 
"tbl_df", "tbl", "data.frame"))

And there is the code I used:

library(dplyr)
library(tidyverse)
library(ggforce)

i <- ceiling(
  length(levels(df$Transect)) / 4) # set the number of pages

pdf("multi_page.pdf", width = 16 / 2.54, height = 12 / 2.54)
SdesGG <- df %>% #launch each time or does not work
  group_by(Transect) %>% #mandatory or need to fortify 
  ggplot(aes(x = oxygen, y = depth, color = Station))  
  geom_line()  
  scale_color_brewer(palette = "Paired")  
  scale_y_reverse()   
  facet_wrap_paginate(~Transect, ncol = 2, nrow = 2, page = i) #ggforce 
dev.off()

I have 180 000 observations, therefore it might be interesting to duplicate the number of row

lapply(df, rep, 1000)

CodePudding user response:

With the page argument you only specify

The page to draw (see ?facet_wrap_paginate)

That's why you get only the last or second page with page = i.

If you want all pages you have to loop over the pages:

library(ggplot2
library(ggforce)

i <- ceiling(
  length(levels(df$Transect)) / 4) # set the number of pages

pdf("multi_page.pdf", width = 16 / 2.54, height = 12 / 2.54)
lapply(seq(i), function(page) {
  SdesGG <- df %>% #launch each time or does not work
    group_by(Transect) %>% #mandatory or need to fortify 
    ggplot(aes(x = oxygen, y = depth, color = Station))  
    geom_line()  
    scale_color_brewer(palette = "Paired")  
    scale_y_reverse()   
    facet_wrap_paginate(~Transect, ncol = 2, nrow = 2, page = page) #ggforce   
})
dev.off()
