Install fails

[markhogue]

Installation with devtools fails with or without commit number. Showing below with a 9 month old commti, but I tried lots in between:
devtools::install_github(repo = "marcusvolz/mathart", commit = "2ca706c")

Error in read.dcf(path) :
Found continuation line starting ' person("Marcus", ...' at begin of record.

By contrast,
devtools::install_github(repo = "marcusvolz/ggart")
works fine. One difference is the DESCRIPTION file has only one authors@R line.

Please help, function not found error

Mark, I don't seem to get this problem when I do a fresh install. It looks like it has something to do with r-lib/devtools#1900 - I've removed indentations in the description file so maybe that will work.

[marcusvolz]

mas192 - I'm not sure why you are getting those errors. Have you loaded the packages?
library(mathart)
library(ggart)
library(ggforce)
library(Rcpp)
library(tidyverse)

[mas192]

Yes, I did!!

[mas192]

I'll reinstall mathart and see if it fixes it

[mas192]

I see all the variable, but now I dont see the plot, sorry,
df <- mollusc()
df1 <- df %>% mutate(id = 1)
df2 <- df %>% mutate(id = 2)
df3 <- df %>% mutate(id = 3)

p <- ggplot() +
geom_point(aes(x, y), df1, size = 0.03, alpha = 0.03) +
geom_path( aes(x, y), df1, size = 0.03, alpha = 0.03) +
geom_point(aes(x, z), df2, size = 0.03, alpha = 0.03) +
geom_path( aes(x, z), df2, size = 0.03, alpha = 0.03) +
geom_point(aes(y, z), df3, size = 0.03, alpha = 0.03) +
geom_path( aes(y, z), df3, size = 0.03, alpha = 0.03) +
facet_wrap(~id, nrow = 2, scales = "free") +
theme_blankcanvas(margin_cm = 0.5)

ggsave("mollusc01.png", width = 80, height = 80, units = "cm")

am I doing something wrong?

[marcusvolz]

Is there not a png file called "mollusc01.png" in your working directory? (Type getwd() to see where your working directory is.)

[mas192]

Yes I see the file but is empty

[marcusvolz]

ggsave can take some time to generate the plot (5+ minutes on my machine). In the meantime it might look like an empty file. It seems to work ok on my machine - sorry I can't be of more help.

[mas192]

Oh okay that makes, sense, thanks!!!!

[mas192]

you are right it worked, thanks

[markhogue]

Thank you so much, Marcus. It works now.
Sorry I took so long to reply. I'm new to github and thought I was going to see a notification in my email.
