I would store the data as a "ts" object with NAs in it. If x is the "data.frame" above, you could do

## create regular time scale
y <- data.frame(year = 1986:2004)
## merge data
lgd <- merge(x, y, by = "year", all = TRUE)[,2] ## create ts object
lgd <- ts(lgd, start = 1986)
## plot
plot(lgd, type = "o", pch = 16)
