Have a look at the zoo package. There are three vignettes (pdf documents)
included with the package that give many examples of its use. Also
see ?read.zoo, ?plot.zoo and ?xyplot.zoo
You will need something like:
library(zoo)
z - read.zoo(myfile, ...whatever...)
plot(z)

I have a set of modeled climate data recorded at irregular intervals. The
format of the data is such that there are monthly measurements for the years
2000, 2020, 2050, 2080, etc. Therefore I have 12 regular records, a skip of
some number of years, then 12 more monthly records, another skip, and so
on I created a dataframe from .txt with the read.table() command. For
starters I need to simply plot the data as a timeseries with DATE on the x
axis. I am just getting my feet wet with R, so I'm struggling a bit to
follow the help() pages. Can anyone point me in the proper direction? Thank
you in advance.
Here is a piece of the dataframe:
