[R] Time Series

[arun]

Hi Wayne,

As John mentioned, it is not clear about your expectations.  May be this helps:
library(xts)
x2New <- xts(test[,-1], order.by=test[,1])
library(xtsExtra)
plot(x2New,screens=1,auto.legend=TRUE)

A.K.

What were you expecting to get? Just plotting the time series without labels etc, since I am getting some weird error messages about pch having a “unexpected ',' in " pch="16" and I am too lazy to bother debugging it I get a four panel plot (see attached). This does not seem make any sense to me since I don't see why Date is plotted, but as I say I know nothing about time series.

However the data did come through okay. Presumably test$Date is a date. It reads in as a factor for me which is one reason for using dput() which maintains the structure of the data.

Below is what I think your data looks like in dput() format.

Sorry not to be of more help.

test <- structure(list(Date = structure(c(15657, 15664, 15678, 15700, 15713, 15720, 15734, 15741, 15755, 15769, 15783, 15790, 15811, 15832, 15839, 15853, 15867, 15880, 15895, 15902, 15916, 15930, 15944, 15951, 15958, 15965, 15972, 15979, 15986, 16000, 16014, 16021, 16028, 16035, 16042, 16049, 16056, 16065, 16077, 16084, 16091, 16105, 16112, 16126, 16141, 16147, 16154, 16161, 16175, 16189, 16203), class = "Date"), Inr = c(2.2, 2.5, 2.4, 2.3, 2.1, 1.9, 1.9, 3.3, 2.6, 2.7, 3.1, 2.4, 2, 2.5, 2.3, 2.4, 2.3, 2.3, 2.1, 2.4, 3.6, 3, 1.3, 2.6, 1.9, 3.4, 2.4, 2.2, 2.9, 2.8, 2.1, 2.2, 2.2, 3, 2.7, 2.3, 2.7, 2.9, 2.7, 2.6, 2.6, 3.3, 2.6, 2.8, 2.9, 3.5, 2.8, 2.7, 2.5, 2.8, 2.3), Wdose = c(30, 32.5, 32.5, 35, 35, 35, 25, 40, 37.5, 37.5, 37.5, 32.5, 37.5, 35, 35, 35, 35, 35, 35, 42.5, 40, 35, 25, 40, 32.5, 35, 32.5, 35, 37.5, 35, 35, 37.5, 37.5, 40, 37.5, 37.5, 40, 40, 40, 40, 37.5, 37.5, 40, 37.5, 40, 40, 32.5, 35, 35, 35, 35), Deldose = c(NA, 2.5, 0, 2.5, 0, 0, -10,

John:

The data that I sent you did you receive it? If so what thoughts or suggestions do you have for plotting the time series?

I am not sure what is going wrong and getting multi plot of same.

Thank you

No raw data.  Sent is as text (csv) or use dput() to include it in the email.
