R xlab and ylab in xts plot

Question

Plotting an xts should be really easy, but I can't seem to get the xlab, and ylab to work..

ylab="Price"
xlab="Date"


plot(x = basket[, 1], lty="dotted", xlab = xlab, ylab = ylab, col = "mediumblue", lwd = 2) 
title("Cumulative")

This will plot the figure, but without any labels on the x- and y-axis.

There must be an easy solution to this. The plot looks as it should besides that issue. I have tried with xts.plot, zoo.plot, xyplot but none seem to do the trick.

Data sample

I know this might not be exactly what you had in mind, but it gets the job done. Plus, you get to work with ggplot2 which way better than the standard plotting system. In addition, I am using ggfortify which extends ggplot() capabilities to handle time series.

library(xts)
library(zoo)
library(ggfortify)   
library(ggplot2)

myts = structure( 
  c(1, 1.01463414634146, 0.926829268292683, 0.970731707317073, 
    0.953658536585366, 1, 0.998263888888889, 1.01159722222222, 1.05076388888889, 
    1.05034722222222, 1, 1.00178890876565, 0.985688729874776, 1.04293381037567, 
    1.04651162790698, 1, 0.976675478152698, 0.990359197636448, 1.06515316436013, 
    1.04571606282071), 
  class = c("xts", "zoo"), 
  index = structure(c(946944000, 947030400, 
                      947116800, 947203200, 
                      947462400), 
                    tzone = "UTC", 
                    tclass = "Date"), 
  .Dim = 5:4, .Dimnames = list(NULL, 
                               c("new.close", 
                                 "new.close.1", 
                                 "new.close.2", 
                                 "new.close.3" ) ) 
)

autoplot( myts[ , 1], xlab = "Date", ylab = "Price" )

It is plot.zoo, not zoo.plot. These all work for me:

library(xts)

plot(as.zoo(basket[, 1]), xlab = "X", ylab = "Y")

plot.zoo(basket[, 1], xlab = "X", ylab = "Y")

library(lattice)
xyplot(basket[, 1], xlab = "X", ylab = "Y")

library(ggplot2)
autoplot(basket[, 1]) + xlab("X") + ylab("Y")

Note

basket <-
structure(c(1, 1.01463414634146, 0.926829268292683, 0.970731707317073, 
0.953658536585366, 1, 0.998263888888889, 1.01159722222222, 1.05076388888889, 
1.05034722222222, 1, 1.00178890876565, 0.985688729874776, 1.04293381037567, 
1.04651162790698, 1, 0.976675478152698, 0.990359197636448, 1.06515316436013, 
1.04571606282071), class = c("xts", "zoo"), index = structure(c(946944000, 
947030400, 947116800, 947203200, 947462400), tzone = "UTC", tclass = "Date"), .Dim = 5:4, .Dimnames = list(
    NULL, c("new.close", "new.close.1", "new.close.2", "new.close.3"
    )))

Something is clearly off with my xts plot settings for xts. None of them plots anything on the X and Y axis. I did try and remove the heading of the interval for which the plot was taken over, and that must have messed up something. The ggplot2 does work though, so I guess I will have to work with that then. Thx! – Anders May 05 '20 at 17:52
Start a fresh instance of R using `R --vanilla` to be sure that nothing is pulled in. Then copy and paste `basket `from the Note at the end of the answer and then copy and paste the code in the answer. – G. Grothendieck May 05 '20 at 18:39
