Unexpected behaviour of windowsFonts() when Rdevga is edited

csrabak-3
Hi folks,
 

Running R in a Windows machine:
 
> sessionInfo()
R version 3.4.2 (2017-09-28)
Platform: x86_64-w64-mingw32/x64 (64-bit)
Running under: Windows 8.1 x64 (build 9600)
 
Matrix products: default
 
locale:
[1] LC_COLLATE=Portuguese_Brazil.1252  LC_CTYPE=Portuguese_Brazil.1252   
[3] LC_MONETARY=Portuguese_Brazil.1252 LC_NUMERIC=C                      
[5] LC_TIME=Portuguese_Brazil.1252    
 
attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base     
 
loaded via a namespace (and not attached):
[1] compiler_3.4.2  nlme_3.1-131    grid_3.4.2      lattice_0.20-35
[5] fortunes_1.5-4 
 
Where Rdevega was edited as folows:
 
# The system-wide copy is in rwxxxx/etc.
# A user copy can be installed in `R_USER'.
 
# Format is 
# [TT] face:style
# where style is plain, bold, italic or bold&italic.
# If 'TT' is present, only TrueType/OpenType fonts are searched.
# Remarks:
#   (a) Windows graphics engine can only rotate TrueType fonts;
#   (b) Only the first 32 fonts will be used.
 
<Rdevga>
TT Verdana : plain
TT Verdana : bold
TT Verdana : italic
TT Verdana : bold&italic
 
# Please, don't change the following definition. The plot math engine
# assumes that font5 contains greek letters and math symbols
TT Symbol: plain
 
TT Times New Roman : plain
TT Times New Roman : bold
TT Times New Roman : italic
TT Times New Roman : bold&italic
 
TT Courier New: plain
TT Courier New: bold
TT Courier New: italic
TT Courier New: bold&italic
 
TT Century Gothic : plain
TT Century Gothic : bold
TT Century Gothic : italic
TT Century Gothic : bold&italic
 
TT Matisse ITC: plain
TT Wingdings: plain
</Rdevga>
 
 
When I check the font family:
 
> windowsFonts()$sans
[1] "TT Arial"
 
I find unexpected that the family name is still "TT Arial" although the font when ploting or using text() for annotation in graphics employs the font selected in the Rdevga file (Verdana in this case).
 
I searched all documentation and the Net and the answer to this puzzle eluded me, so if not a bug, I find this very unexpected!
 
TIA
