Dear All,
>From :
?maps::map
we have :
map(database = "world", regions = ".", exact = FALSE,
boundary = TRUE,
interior = TRUE, projection = "", parameters = NULL,
orientation NULL,
fill = FALSE, col = 1, plot = TRUE, add = FALSE, namesonly = FALSE,
xlim = NULL, ylim = NULL, wrap = FALSE, resolution = if (plot) 1
else 0,
type = "l", bg = par("bg"), mar = c(4.1, 4.1,
par("mar")[3], 0.1),
myborder = 0.01, namefield="name", lforce="n", ...)
My query is the regex regions="." will match any single character.
Should
it not be regions =".*" to be precise? Although I do realize that
"." will
also match any string except "" (the empty string)? To be precise it
should
be ".*" which can match an empty string as well ANY arbitrary string.
I was
confused for a short while when I first read this. Look forward to
clarification on this.
Many thanks,
Ashim
