Description

class of TreeRingShape

Slots

P_filename

character. file name of shape file (P) for tree ring points

P_id.tag

character. column name of id in shape file (P), default is 'id'

P_ring.tag

character. column name of ring no.(ordinaly year,outermost=0) in shape file (P), default is 'ring'

P

data.frame. radial tree ring points (x,y,id,yr,r,deg)

P00

numeric. x,y coordinates c(px00,py00) of tree ring center point, ordinarily a pith in a disk, a point of id==0 in P

n_id

numeric. number of radial measurement points, length(unique(P$id))-1 (omit a original point id=0)

YR_P

numeric. total number of tree rings, unique(P$ring)

L_filename

character. file name of shape file (L) for tree ring lines

L_ring.tag

character. column name of ring no.(ordinaly year,outermost=0) in shape file (L), default is 'ring'

L

list. x,y coordinates of representative tree rings

L_

data.frame. x,y coordinates of representative tree rings

YR_L

numeric. cumulative tree rings number(year) from 0 (cambium layer) of L =dbf$ring, names(L)

ln

numeric. total number of representative tree rings, length(L)

L2_filename

character. file name of shape file (L2) for tree ring lines interpolated

L2

list. x,y coordinates of representative + interpolated tree rings

n_YR

numeric. total number of representative + interpolated tree rings = unique(P$yr), length(L2)
