opening RnetCTF file on R, code error no dimension "HAS NO DIMVAR"

Question

I am tryng to open specific lists from netCTF file that I have already succeed to open in R.

I want to plots the variables: y = Depth, x= Latitude, fill by the temperature data. The variable LATITUDE has lenght of 42 (integer 1) The variable " DEPTH" has no dimension: # DEPTH Size:3617 (no dimvar) but has length 3617 (integrer 1) The variable TEMP is size : (integer 2) 3617 42

I don't know how to convert the DEPTH variable as readable... Or I could use the variable "PRESSURE" which correspond of size : (integer 2) 3617 42, as depth, as the pressure is the result from the latitude and depth.

I am using the package:

library("raster")
library("ncdf4") 
library("RNetCDF") ```
