Convert unit on x direction in data coordinate
1 2 3 4 5 | convert_x(x, unit = c("mm", "cm", "inches"),
sector.index = get.cell.meta.data("sector.index"),
track.index = get.cell.meta.data("track.index"),
h = get.cell.meta.data("ycenter", sector.index = sector.index,
track.index = track.index))
|
x |
a numeric vector |
unit |
supported units, only "mm", "cm", "inches" |
sector.index |
index for the sector where the conversion is applied |
track.index |
index for the track where the conversion is applied |
h |
since the width of the cell is not identical from the top to the bottom in the cell, the position on y direction needs to be specified. By default it is at the middle point on y-axis |
A vector of numeric values which are measured in the specified data coordinate

convert_y
converts on y direction.
