Insert the slave so that it occupies the n th row in the grid. Row numbers start with 0. If this option is not supplied, then the slave is arranged on the same row as the previous slave specified on this call to grid , or the first unoccupied row if this is the first slave. Insert the slave so that it occupies n rows in the grid. The default is one row.
Style is a string that contains zero or more of the characters n , s , e or w .
The string can optionally contain spaces or commas, but they are ignored. The default is '' , which causes the slave to be centered in its cavity, at its requested size. The return value consists of 4 integers. If a single column and row is specified on the command line, then the bounding box for that cell is returned, where the top left cell is numbered from zero. If both column and row arguments are specified, then the bounding box spanning the rows and columns indicated is returned.
