R: Plot Argo Data

plot,argo-method {oce} | R Documentation

## Plot Argo Data

### Description

Plot a summary diagram for argo data.

### Usage

    ## S4 method for signature 'argo'
    plot(x, which = 1, level, coastline = c("best",
      "coastlineWorld", "coastlineWorldMedium", "coastlineWorldFine", "none"),
      cex = 1, pch = 1, type = "p", col, fill = FALSE,
      projection = NULL, mgp = getOption("oceMgp"), mar = c(mgp[1] + 1.5,
      mgp[1] + 1.5, 1.5, 1.5), tformat, debug = getOption("oceDebug"), ...)

### Arguments

`x` | object inheriting from `argo-class`.
`which` | list of desired plot types, one of the following. Note that `oce.pmatch` is used to try to complete partial character matches, and that an error will occur if the match is not complete (e.g. `"salinity"` matches to both `"salinity ts"` and `"salinity profile"`.). `which=1`, `which="trajectory"` or `which="map"` gives a plot of the argo trajectory, with the coastline, if one is provided. `which=2` or `"salinity ts"` gives a time series of salinity at the indicated level(s) `which=3` or `"temperature ts"` gives a time series of temperature at the indicated level(s) `which=4` or `"TS"` gives a TS diagram at the indicated level(s) `which=5` or `"salinity profile"` gives a salinity profile of all the data (with S and p trimmed to the 1 and 99 percentiles) `which=6` or `"temperature profile"` gives a temperature profile (with T and p trimmed to the 1 and 99 percentiles)
`level` | depth pseudo-level to plot, for `which=2` and higher. May be an integer, in which case it refers to an index of depth (1 being the top) or it may be the string "all" which means to plot all data.
`coastline` | character string giving the coastline to be used in an Argo-location map, or `"best"` to pick the one with highest resolution, or `"none"` to avoid drawing the coastline.
`cex` | size of plotting symbols to be used if `type='p'`.
`pch` | type of plotting symbols to be used if `type='p'`.
`type` | plot type, either `"l"` or `"p"`.
`col` | optional list of colors for plotting.
`fill` | Either a logical, indicating whether to fill the land with light-gray, or a color name. Owing to problems with some projections, the default is not to fill.
`projection` | indication of the projection to be used in trajectory maps. If this is `NULL`, no projection is used, although the plot aspect ratio will be set to yield zero shape distortion at the mean float latitude. If `projection="automatic"`, then one of two projections is used: stereopolar (i.e. `"+proj=stere +lon_0=X"` where `X` is the mean longitude), or Mercator (i.e. `"+proj=merc"`) otherwise. Otherwise, `projection` must be a character string specifying a projection in the notation used by the `link[rgdal]{project}` function in the rgdal package; this will be familiar to many readers as the PROJ.4 notation; see `mapPlot`.
`mgp` | 3-element numerical vector to use for `par(mgp)`, and also for `par(mar)`, computed from this. The default is tighter than the R default, in order to use more space for the data and less for the axes.
`mar` | value to be used with `par`("mar").
`tformat` | optional argument passed to `oce.plot.ts`, for plot types that call that function. (See `strptime` for the format used.)
`debug` | debugging flag.
`...` | optional arguments passed to plotting functions.
