Quick spatial image of prism data

Source: R/pd_image.R
pd_image.Rd

pd_image() makes a spatial image plot of the specified prism data (single variable and time step.). It is meant for rapid visualization, but more detailed plots will require other methods.

prism_image() is the deprecated version of pd_image().

Usage

pd_image(pd, col = "heat")

prism_image(prismfile, col = "heat")

Arguments

pd, prismfile

the name of a single file to be plotted, this is most easily found through prism_archive_ls() or prism_archive_subset().

col

the color pattern to use. The default is heat, the other valid option is "redblue".

Value

Invisibly returns gg object of the image.

)

# get June 5th
pd <- prism_archive_subset("tmean", "daily", dates = "2013-06-05")

# and plot it
