Hi. This may be a straight-forward question...
I have a time series from 1950 to 2000 (by year) with missing values.
Sometimes only a year has value and the adjacent years have missing data, e.g.
1950 2.7
1951
1952
1953 3.4
1954
1955
1956 2.9
1957 3.6
1958 2.7
When I use plot (type='l'), the line can't connect the 'stand-alone' years. Is
there a way I have have R to skip over the NA and draw a line with the points
available?
Hi Kitty,
Assuming that the above is a data frame with two columns, the second of
which is named "value":
plot(my.data.frame[!is.na(my.data.frame$value),],type="l")
