Error possibly related with environments/namespace
Hello all, I've got a problem with a function in a R package I've developed (MetaLandSim). One of the outputs of my function is the plotting of four images (combining a graph and a map). This plotting is made in a graphical device, with the graph in one side and the map in the other. My function works perfectly fine until it has to plot the map. Then it stops and I get an error.

How to sort TWO columns ?
Dear ALL, I fear my question has already been answered many times before, but I haven't fund that in archives... I am working on spatial datasets and, in most arrays I'm handling, there are two columns dedicated to (x,y)-coords. For different reasons - notably to draw image() plots, I need to have these two columns sorted in increasing order. But sort() and order() seem to apply to

loess line predicting number where the line crosses zero twice
These data represent stream channel cross-sectional surveys. I would like to be able to find the measurement on the tape (measure) where the Bank Full Depth (bkf_depths) is 0. This will happen twice because the channel has two sides. I thought fitting a loess line to these data and then predicting the measurment number would do it. I was wrong. Below is my failed attempt. My naive thought is
