plot,rtoi,Date-method: Plot an rtoi object

Description

Plot (a map of) the values of an rtoi or records object.

Usage

# S4 method for rtoi,Date
plot(
  x,
  y,
  ...,
  variable = "rgb",
  band_name = c("red", "green", "blue"),
  verbose = FALSE,
  xsize = 250,
  ysize = 250
)
# S4 method for rtoi,character
plot(
  x,
  y,
  ...,
  variable = "rgb",
  product = "ALL",
  band_name = c("red", "green", "blue"),
  dates = NULL,
  verbose = FALSE,
  xsize = 250,
  ysize = 250
)
# S4 method for records,ANY
plot(x, y, verbose = FALSE, ...)
# S4 method for rtoi,missing
plot(x, y, verbose = FALSE, ...)

Value

tmap plot.

Arguments

x

an rtoi or records.

y

character argument. The valid values are "dates", "preview", or "view".

...

additional arguments.

variable

character argument. The variable to be plotted. By default, a color (RGB) variable is selected .

band_name

character vector argument. Enables false color plots. By default, usual bands are selected c("red","green","blue").

verbose

logical argument. If TRUE, the function prints the running steps and warnings.

xsize

the number of samples on the horizontal axis.

ysize

the number of samples on the vertical axis.

product

character argument. The product name to be plotted.

dates

date vector argument. The dates to be plotted.
