[R] Multiple Plots using ggplot

Hi All,

Thanks for the help. I want to plot some of the columns on the same graph
not all of them. Sorry, I failed to follow the instructions. Here is the
output of *dput()* but I don't know how it works.

> dput(head(data))structure(list(Date = structure(c(-6575, -6209, -5844, -5479,
-5114, -4748), class = "Date"), Number.of.Rain.Days = c(86L,
96L, 114L, 119L, 123L, 124L), Total.rain = c(1139.952, 977.646,
1382.014, 1323.086, 1266.444, 1235.964), Start.of.Rain..i. = c(92L,
98L, 92L, 100L, 92L, 92L), Start.of.Rain..ii. = c(239L, 98L,
92L, 100L, 92L, 92L), Start.of.Rain..iii. = c(112L, 112L, 120L,
125L, 119L, 112L), Start.Rain..iv. = c(112L, 112L, 120L, 174L,
119L, 112L), End.of.Rain.Season = c(228L, 229L, 240L, 228L, 228L,
228L)), .Names = c("Date", "Number.of.Rain.Days", "Total.rain",
"Start.of.Rain..i.", "Start.of.Rain..ii.", "Start.of.Rain..iii.",
"Start.Rain..iv.", "End.of.Rain.Season"), row.names = c(NA, 6L
), class = "data.frame")

 I think I need subset function then melt. Here is the approach I used:

d <- subset(df1,
select=c(Date,Start.of.Rain..i.,Start.of.Rain..ii.,Start.of.Rain..iii.))
d
d2 <- melt(d ,  id = 'Date', variable_name = 'Start')

ggplot(d2, aes(Date,value)) + geom_line(aes(colour = start),type = "h")

 but the error is:

Don't know how to automatically pick scale for object of type
function. Defaulting to continuousError in data.frame(colour =
function (x, ...)  :
  arguments imply differing number of rows: 0, 183


Thanks,

Frederic.

The x-axis must be date column. Thanks!
