javascript - R leaflet package produces blank (grey) map [Ubuntu 14.04] -

-

i tried out examplecode leaflet package doc:

devtools::install_github("rstudio/leaflet");library(leaflet) m <- leaflet() %>%   addtiles() %>%  # add default openstreetmap map tiles   addmarkers(lng=174.768, lat=-36.852,              popup="the birthplace of r") m  # print map

but produced grey, blank map in rstudio viewer, in firefox 38.0. maybe has ubuntu?

here sessioninfo:

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...
