Whenever I try to use symbols in a plotmath expression in R, I get white squares. For example, when I run demo(plotmath), I get the following.
Does anyone have an idea where the problem may lie? I am using R 3.4.1 in Rstudio on Mac OS X 10.11.6.
Update:
As mentioned in the comments, it seems to be an issue with my fonts.
When I look at Symbol, I have two "Symbol Regular"s, and the second one appears as question marks when viewing both together. However, when I click on the second one individually, the fonts appear normally. I tried to validate fonts and remove duplicates, but Font Book did not detect any problems. What should I do?
If you go to Fontbook.app and examine the Symbol font, is it perhaps duplicated or can you see any other evidence of corruption? – 42- 25 mins ago
#42- Thanks very much, it does seem to be an issue with the Symbol font. I listed what I see above; do you know what I should do with the font to fix it? – angryavian 9 mins ago
Delete it. It will get replaced from some magic Apple storeroom buried deep in the bowels of the System.
I don't know how this happens, but it used to happen to me fairly often. Doesn't seem to be happening lately. I remain puzzled. I'm guessing there may be answers at Ask Different (but I didn't find an answer.) Whatever the mechanism it's been around for a long, long time:

There are these things like p_i1635_3_ and func_145748_c_ and things like that in minecraft forge 1.7.10. What are they and how do I know what to enter in place of their value?
Those are SRG names. They're halfway in between the truly obfuscated names that Minecraft shipped with, and the MCP names that are completely human readable. The conversion of SRG to MCP names was a long ongoing process, and it wasn't completely finished in 1.7.10 (and never will be since it's over 7 years old now). To figure out what they are, either look at the context it appears in, or look at the equivalent code in a newer version of Minecraft.
I'm trying to assign the result of a chain matrix multiplication in Maxima to a new variable. I'm not sure as a new user why line %o6 isn't the same as the previous and fully evaluate the chain. Also why when I enter the new variable name "B" I simply have "B" returned back to me and not ([32, 32], [32, 32]). Basic questions I know but I've searched the documentation for a number of hours, and tutorials, and the syntax that I'm supposed to use here to get what I guess I was expecting as output, is still unclear to me.
I can't tell for sure, but it appears that the problem is that B : A.A.A is entered holding the shift key for at least one of the spaces, and Shift+Space is interpreted as non-breaking space instead of ordinary space. This appears to be a known bug or at least a serious misfeature in wxMaxima; see: https://github.com/wxMaxima-developers/wxmaxima/issues/1031
(I say misfeature because Shift+Space --> non-breaking space is documented in the wxMaxima documentation, but it seems like a classic example of "bad affordance"; it is all too easy to do the wrong thing without knowing it. Anyway this is just my opinion.)
I built wxMaxima from current source code and it appears that Shift+Space is now not interpreted as non-breaking space in code, so B : A.A.A should have the expected effect even if shift key is held while typing space. The current version is 19.07.0-DevelopmentSnapshot. I poked through the commit log a bit, but I can't figure out which commit changed the behavior of Shift+Space, so it's possible that the problem is not fixed and it is just fortuitous that I am not encountering it.
There are two workarounds, if one doesn't want to hazard an upgrade. (1) Omit spaces. (2) Be careful to only type space without shift.
Hope this is helpful in some way.
I was reading a question in SO and came up with the !! operator. Ive been working with R for some time and never have seen it. First, Ive search for questions about it, and couldnt find one in SO (so this may be a duplicate). Also, go back to diferent R operators post and pages, and no one says anything of it.
In the question, the !! preceded an R oject, like:
> !!object
Thanks for the help.
P.D.: If its a duplicate, please close.
The first problem is The original language is english, "CORN STARCH PROCESSING LINE" is translated into Russian with a neural machine. The result is "ЛИНИЯ ОБРАБОТКИ КУХНЯ", which is larger difference from the original language. And the second problem is the original language is english, "SULLAIR COALESCING FILTER 02250153-324", translated into Arabic with the neural machine, the result is "SULLAIR COALESCING FILTER 02250153-324", not Arabic.how can I solve this problem?
Regarding the Russian translation, the Cloud Translation API is giving a result as much accurate as it is possible. Those results are being constantly improved and updated.
For the Arabic translation part, there seems to be an issue with using the - symbol in the numbers. Because if you remove it or use any other symbol then the words will be translated to Arabic as expected.
I have created an issue tracker for that, you can follow this link to get updates on the fix. Keep in mind that there is no ETA on when the fix will be ready, so as a work around for now, just replace the - symbol with _ symbol and the words will be translated to Arabic.
Some time ago I found an ISO-standard(I think) which described boundaries to use in order to determine a word in a text based on different languages.
Is this something that I have made up in my dreams? Or can you help me find it? I've tried google but I didnt find anything.
Thanks,
BJ
Found what I was looking for. Sorry, no ISO-standard but an Unicode Standard Annex:
