Why is this not plotting? I keep getting the same error.

Looks like you have a + at the beginning of line 10 that shouldn't be there

Thanks. I tried that but it didn't work. I'm knew to R so I must have missed a step along the way.

This code runs fine. What's different from yours? When you say you tried what I suggest, what did you try? When you're having unexpected results in R, another good approach is to restart your R session and try running again (under the Session menu in RStudio). (Note that I removed the devtools::install_github('bbc/bbplot') line because you don't need to reinstall the package every time you run the code.)

pacman::p_load('dplyr', 'tidyr', 'gapminder',
               'ggplot2',  'ggalt',
               'forcats', 'R.utils', 'png', 
               'grid', 'ggpubr', 'scales',
               'bbplot')

line_df <- gapminder %>%
  filter(country == "Malawi") 

#Make plot
line <- ggplot(line_df, aes(x = year, y = lifeExp)) +
  geom_line(colour = "#1380A1", size = 1) +
  geom_hline(yintercept = 0, size = 1, colour="#333333") +
  bbc_style() +
  labs(title="Living longer",
       subtitle = "Life expectancy in Malawi 1952-2007")

I got it to work when I put: plot (line <-

One more question. How do I get R to pull an image-logo from my files in the final line of code. I've tried using a web link to our website, but also .png from my harddrive. Do I need to load the image first? Possibly the image I'm using is just too big, but I didn't think that makes sense considering it's a .png vector

finalise_plot(plot_name = my_line_plot,
source = "Source: Gapminder",
save_filepath = "filename_that_my_plot_should_be_saved_to.
png",
width_pixels = 640,
height_pixels = 450,
logo_image_path = "

Here's the actual code that I can't get to plot:

plot (finalise_plot(plot_name = "line",
source = "Source: Gapminder",
save_filepath = "Malawi.png",
width_pixels = 640,
height_pixels = 450,
logo_image_path = "~Orionlogo.png"))

Ok, let's take a step back here because you have a few things going on at once.

First, wrapping plot() around your code is not responsible for fixing your previous issue. It is also unnecessary, and I do not recommend it. What's happening underneath the hood is that plot() is explicitly printing the object. If you've got code that saves to an object (line <- #{some plot code}, it won't print by default. You need to look at line by running it either in a script or in the console pane. If you look at the code I put above, line, the plot object we created, is the last thing to run. That's why it printed the plot.

Moving on to your second question, finalise_plot() shouldn't work with plot(), as it is trying to save a file (Malawi.png), not plot something in your R session. So remove that part surrounding it.

Second, you have plot_name = "line" but it should be plot_name = line. Because line is an object that lives in your R session, you don't need to wrap it in quotation marks. I can't tell you if your company logo will work here because I don't have the file, and I don't know where it is on your computer in relation to your R session. But if it's at "~Orionlogo.png" it should now appear on the plot in the file Malawi.png.

Since this is getting a little more detailed, I'm also going to skip ahead to something I was going to bring up after we resolved your issue, which is that GitHub issues are not generally a good place to ask questions like this. You might like asking for help at a place like RStudio Community. Additionally, you can maximize your chances of getting help by sharing your code in a reproducible example. Here is a good guide on preparing R questions, as well as a list of places that are good for asking for help: https://www.tidyverse.org/help/

If these don't fix your issue, my recommendation would be to post at RStudio Community. You can feel free to tag me (my username is malcolm there) for help. The reason I am suggesting that is that GitHub issues is generally a place to file bug reports or feature requests, which this is not.

So if this doesn't solve your problem, please close this issue and ask for help there (maybe with a link to this issue).

Dude, you're the man. Thanks so much!
