ROMS single slice 2D layer Extract a data layer from ROMS by name and 4-D slice.

romsdata always works in the first two dimensions (x-y), the more specialist functions will work in the space indicated by their name roms_xy, roms_xt and so on.

roms_xy(x, varname = "", slice = c(1L, 1L), transpose = TRUE, ...)

roms_xz(x, varname = "", slice = c(1L, 1L), transpose = TRUE, ...)

roms_xt(x, varname = "", slice = c(1L, 1L), transpose = TRUE, ...)

roms_yz(x, varname = "", slice = c(1L, 1L), transpose = TRUE, ...)

roms_yt(x, varname = "", slice = c(1L, 1L), transpose = TRUE, ...)

roms_zt(x, varname = "", slice = c(1L, 1L), transpose = TRUE, ...)

romsdata(x, varname = "", slice = c(1L, 1L), transpose = TRUE, ...)

romsdata2d(x, varname = "", slice = c(1L, 1L), transpose = TRUE, ...)

romsdata3d(
  x,
  varname = "",
  slice = 1L,
  transpose = TRUE,
  verbose = TRUE,
  ...,
  lvar = 4L
)

Arguments

x	ROMS file name
varname	name of ROMS variable
slice	index in w and t (depth and time), defaults to first encountered
transpose	the extents (ROMS is FALSE, Access is TRUE)
...	unused
verbose	be chatty
lvar	passed to raster::brick to specify 3rd or 4th dimension

Value

RasterLayer

Examples

#x <- raadtools:::cpolarfiles()$fullname[1]
#plot(roms_xy(x, "u"))
#plot(roms_xz(x, "u", slice = c(392L,1L)), asp = NA)
#plot(roms_xt(x, "u", slice = c(392L,1L)), asp = NA)

#plot(roms_yz(x, "u"))
#plot(roms_yt(x, "u", slice = c(1L,1L)), asp = NA)
#plot(roms_zt(x, "u", slice = c(1L, 392L)), asp = NA)
