sort won't work with my mosaicplot

[cupricfae]

I have this graph created with the code:

mosaicplot(table(Vowel, Jacc$Jacc), 
           color = blues9,
           main = "Japanese Knowledge and Accuracy compared to Vowel Features")

However, I wanted to reorganize the columns so that they would be sorted by long-short pairs instead of by alphabetical. My first attempt at code for it looked like this:

mosaicplot(table(Vowel, Jacc$Jacc), 
  color = blues9,
  main = "Japanese Knowledge and Accuracy compared to Vowel Features",
  sort = "long-a", "short-a", "long-i", "short-i", "long-o", "short-o", "long-u", "short-u")

Vowel is a name for what refers to Quality and Length of vowels (short-a, long-a, short-i, long-i, etc etc) within the Jacc data set, and Jacc refers to knowledge of Japanese + accuracy.

the error I get is:

Error in -rev(shade) : invalid argument to unary operator

I asked a professor and got a suggestion to try this code:

mosaicplot(table(Vowel, Jacc$Jacc), 
           color = blues9,
           main = "Japanese Knowledge and Accuracy compared to Vowel Features",
           sort = c("long-a", "short-a", "long-i", "short-i", "long-o", "short-o", "long-u", "short-u”))

however now i get a very strange error that, as far as I can tell is due to r studio parsing this as starting with the sort as the head of the command?

+ mosaicplot(table(Vowel, Jacc$Jacc), 
+            color = blues9,
+            main = "Japanese Knowledge and Accuracy compared to Vowel Features",
Error: unexpected symbol in:
"           color = blues9,
           main = "Japanese"
>            sort = c("long-a", "short-a", "long-i", "short-i", "long-o", "short-o", "long-u", "short-u”))

Does anyone have clues as to how to fix this?

hi @cupricfae

Your error come from a strange quote you put at the end off your code (after short-u). Instead of ..., "short-u” put ..., "short-u".

Now if you want us to test your code, you must put a minimal reprex dataset that we can use. see here:

FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A minimal reproducible example consists of the following items: A minimal dataset, necessary to reproduce the issue The minimal runnable code necessary to reproduce the issue, which can be run on the given dataset, and including the necessary information on the used packages. Let's quickly go over each one of these with examples: Minimal Dataset (Sample Data) You need to provide a data frame that is small enough to be (reasonably) pasted on a post, but big enough to reproduce your issue. Let's say, as an example, that you are working with the iris data frame head(iris) #> Sepal.Length Sepal.Width Petal.Length Petal.Width Species #> 1 5.1 3.5 1.4 0.…

Hope it help

Hi,

I don't know if this is an error when parsing your code here on the forum, but the very last quotation character you use is not a correct one

"short-u”

This usually happens when you copy code from other sources like word documents that use different quotation characters that are not recognized by R and generate the error. Just replace the quotations with the normal one used in R by removing it and typing " again.

Hope this helps,
