comment Change raster projection in R
We cannot help you if yo do not provide some information on what is actually going wrong. Please provide your R code and the associated error. You likely have a syntax error that can be addressed in short order.

comment Where can I get pointcloud data?
Please clarify "point clouds". Not everybody will be familiar with this terminology. You also do not specify exactly what you are after. Do you want any format, ASCII, LAS, etc? Do you want discrete return lidar, waveform lidar or any source? What features are you after, buildings, vegetation?

comment R: count raster values using another raster as mask
I looked at a way to keep the data raster but I believe that you will run into memory issues in short order.

comment Plotting Raster in R gives error
You need to provide us with more information if you expect a relevant answer and not just speculation. What package are you using, what is the format of the data, what function was used to read it, information regarding the resulting raster object?

I believe that the OP is referring to the legend in the TOC.

@yanes, a KDE results in a floating point raster and as such, there will not be an attribute table.

comment Failure of the code calling the function “rasterize” in R: NAs or no slots
Since a raster has to be numeric I imagine that this is because it has to coerce the column to numeric before conversion. The underlying code is probably assuming a factor when the column is non-numeric. This is good to know.

Sorry, I forgot that the expected input to the rasterize function is a SpatialPolygons object. Try my modification to the rasterize syntax and let me know if it works.

comment How can I link the cells in the excel files to a pixel on my map?
Chicken before the egg. If you have any array of values, organized in rows and columns, exactly how do you get [X,Y] coordinates for each cell? You would need to get the array into a raster format before you could export the data into [X,Y,Z] triplicates.
