seismic.grid.define {RGeostats} | R Documentation |
Create a Time Grid from a Depth Grid, or vice versa
seismic.grid.define(db, ivarv = 1, flag.z2t = 1, x0 = NA, dx = NA, nx = NA, verbose = 0)
db |
The input |
ivarv |
The field index for the Velocity variable in the input |
flag.z2t |
When TRUE, conversion from Depth to Time. When FALSE, conversion from Time to Depth |
x0 |
Vector giving the origin of the resulting grid. If not defined or if the vector does not have the correct dimension (same space as the input Db), the values calculated from the input Db prevail |
dx |
Vector giving the mesh of the resulting grid. If not defined or if the vector does not have the correct dimension (same space as the input Db), the values calculated from the input Db prevail |
nx |
Vector giving the number of grid meshs of the resulting grid. If not defined or if the vector does not have the correct dimension (same space as the input Db), the values calculated from the input Db prevail |
verbose |
Verbose flag |
The resulting db-class
structure, i.e. a Time Grid if flag.z2t=T or a Depth Grid if flag.z2t=F
