Plot NOAA climate data.
Arguments
- ...
Input noaa object or objects.
- breaks
Regularly spaced date breaks for x-axis. See examples for usage. See date_breaks. Default:
NULL(uses ggplot2 default break sformatting)- dateformat
Date format using standard POSIX specification for labels on x-axis. See
date_format()
Details
This function accepts directly output from the ncdc() function,
not other functions.
This is a simple wrapper function around some ggplot2 code. There is indeed a lot you can modify in your plots, so this function just does some basic stuff. Look at the internals for what the function does.

startdate = '2010-05-01', enddate = '2010-10-31', limit=500)
ncdc_plot(out)
ncdc_plot(out, breaks="14 days")
ncdc_plot(out, breaks="1 month", dateformat="%d/%m")
ncdc_plot(out, breaks="1 month", dateformat="%d/%m")
# Combine many calls to ncdc function
out1 <- ncdc(datasetid='GHCND', stationid='GHCND:USW00014895', datatypeid='PRCP',
startdate = '2010-03-01', enddate = '2010-05-31', limit=500)

startdate = '2010-09-01', enddate = '2010-10-31', limit=500)
df <- ncdc_combine(out1, out2)
ncdc_plot(df)
## or pass in each element separately
ncdc_plot(out1, out2, breaks="45 days")
