pointsvg | R Documentation |
Converts 'line', 'rect', 'polygon' and 'polyline' class SVG objects into data frames. ONLY THESE CLASSES OF OBJECTS CAN BE IMPORTED. If you have bezier or spline curves, they will be stored as 'path' class objects that cannot be imported here. The same goes for 'rect' objects that are transformed (rotation, etc...).

file |
a .svg file |
standard |
whether to standardise (centre to (0,0), rescale so that extreme points are at -1 and 1) (T or F) |
keep.ratio |
if the object is to be standardised, whether to keep the x/y ratio (T or F) |
round |
whether to round the coordinates (T or F) |
xdigits |
the number of digits after the decimal to round to for x values |
ydigits |
the number of digits after the decimal to round to for y values |
xinverse |
whether to inverse the plotting for x values (T or F) |
yinverse |
whether to inverse the plotting for y values (T or F) |
warn |
whether you want to be annoyed |
object |
for is.pointsvg, the R object to be checked if it can be considered similarly to a svg outputted by pointsvg |
This function is quite empirical. There is no guarantee it is bug free. If you have .svg files that should work but do not, you can email me: wouterseb@gmail.com
A data.frame with x and y coordinates, ids for each object, and a type, either line (L) or polygon (P)

# To show you how to import, we first have to have a svg file to import. The
#following lines of code will create a svg in a temporary files:
svg.file.directory <- tempfile(fileext = ".svg") # Creates temporary file
writeLines(example.ammonite.svg, svg.file.directory) # Writes svg in the file
print(paste("An example .svg file was created at ", svg.file.directory,
sep = ""))
# The pointsvg function allows to import simple svg drawings into R
ammonite.drawing <- pointsvg(file = svg.file.directory) # Provide file
is.pointsvg(ammonite.drawing)
plot(c(-2,2), c(-2,2), type = "n")
placesvg(ammonite.drawing)
# If you want to import your own .svg file uncomment the following line:
# pointsvg(file.choose())
