How to use WMS in R?
<p>I like to implement a special WMS-layer with <code>leaflet()</code> in <code>R</code>. But I have no success with the WMS-layer I like to use.</p>

<pre><code>library("leaflet")
library("sp")

# this example from the tutorial works
leaflet() %&gt;% addTiles() %&gt;% setView(-93.65, 42.028, zoom = 4) %&gt;%
  addWMSTiles(
    "http://mesonet.agron.iastate.edu/cgi-bin/wms/nexrad/n0r.cgi",
    layers = "nexrad-n0r",
    options = WMSTileOptions(format = "image/png", transparent = TRUE) 
)

# but for my implementation it don't work
leaflet() %&gt;% addTiles() %&gt;% setView(lat = 53.8, lng = 12.6, zoom = 8) %&gt;% 
  addWMSTiles("http://www.umweltkarten.mv-regierung.de/script/mv_a3_wasserschutz_wms.php?", 
              layers = "t2_bib_p", 
              options = WMSTileOptions(format = "image/png")
)
</code></pre>

<p>I assume that there is a problem with the Coordinate Refernce System. Because the WMS-layer I like to use, have not a standard CRS. So I try to expermented with this <code>WMSTileOptions()</code>:</p>

<pre><code>crs=CRS("+init=epsg:5650")
</code></pre>

<p>The idea is to use WMS-Layers as background images for my vector data. The vector data come mainly from shape-files and GPS-data (text files). The purpose is to create maps which i can use in a report. 
If you know other possibles beside <code>leaflet</code> to use WMS in R there are also welcome? </p>
