Re: [R] Fwd: Help: malloc/free deadlock in unsafe signal handler 'Rf_onsigusr1'

The handlers for SIGUSR1 and SIGUSR2 are really intended as an emergency break, not for ordinary programming. These could be rewritten to be safer but that would make them less immediate. Followups would be more appropriate on R-devel. Best, luke On Mon, 1 Aug 2016, Ming Li wrote: Hi all,

Re: [R] Climate data in R

The rnoaa package has the function ncdc_stations which can be used to search for stations in a region. You could use that giving it an extent around the coordinates that you are interested in (add and subtract a small amount from the coordinates), then pass the results from that function

Hi all, I can read the data, but how to plot it using ggplot or something? In this case, x-axis should be longitude, and y-axis should be latitude. I tried to plot using raster function, but the x and y axes are from 0 to 1. Thanks again. The code is like this: pre1 =
