R Code 4.9 histogram fails

[kschulzke]

When I run precis(d) (with R 3.5.3 and R Studio Version 1.1.463), the table prints in the console but the histogram does not render in the plot window. Rather, in the console, I get the text output shown below.

library(rethinking)
data(Howell1)
d <- Howell1
precis(d)
'data.frame': 544 obs. of 4 variables:
mean sd 5.5% 94.5%
height 138.26 27.60 81.11 165.74
weight 35.61 14.72 9.36 54.50
age 29.34 20.75 1.00 66.13
male 0.47 0.50 0.00 1.00

This has something to do with your console not having unicode fonts, I think. It's not related to my package specifically, at least.

I have the same problem as jedijd reported in RStudio with brandnew installations in Windows10. - RStudio is said to support unicode and if I try to "reopen with encoding" the code of
data(Boxes)
precis(Boxes) using UTF-8 this is what I get

'data.frame': 629 obs. of 5 variables:
mean sd 5.5% 94.5%
y 2.12 0.73 1 3
gender 1.51 0.50 1 2
age 8.03 2.50 5 13
majority_first 0.48 0.50 0 1
culture 3.75 1.96 1 8

Thank you for making your work open source! I am enjoying learning from your book.

I have the same issue, also on a new windows 10 machine.
Just to check, I have installed package skimr which also plots histograms with unicode blocks, and it works fine...

This problem is part of a long-standing bug in base R. See these issues: 1 2. One workaround is to save the precis output into a variable, remove the histogram, and then print it. Another workaround is to plot the precis output instead of printing. A workaround for precis(model) is to print/plot a coeftab(model).

Thank you very much for your answer!

I had the same problem. I was going with ap53's suggestion, and the following thread gave me a clue to fix it.
https://stackoverflow.com/questions/44253848/skimr-cant-seem-to-produce-the-histograms

I type this line in rstudio source window.

Sys.setlocale(locale='Chinese')

[jtelleriar]

Yes, the chinese thing worked to me XD
