Check if points in segments
Description:
To check if a number in a range. Return a vector of 0,1 if the
the number in a range(1) or not (0).
Usage:
CheckPoint(pos, start, end)
Arguments:
pos: a vector of numbers of points
start: a vector of numbers of starting position
end: a vector of numbers of ending position
Examples:
aa <- c(2,4,6)
bb1 <- c(1,5,7)
bb2 <- c(3,8,10)
#too see if 2,4,6 in range 1-3,5-8,7-10
CheckPoint(aa,bb1,bb2)
===================================================
Check if segments contain point
Description:
To check if a range contains points. Return a vector of 0,1 with
1 = contain points, 0 = not contain points.
Usage:
CheckRange(pos, start, end)
Arguments:
pos: a vector of numbers of points
start: a vector of numbers of starting position
end: a vector of numbers of ending position
Examples:
aa <- c(2,4,6)
bb1 <- c(1,5,7)
bb2 <- c(3,8,10)
# to see if range 1-3,5-8, 7-8 contain 2,4,6
CheckRange(aa,bb1,bb2)
=====================================================
Check if segments contain point
Description:
To map points into segmentation and return a dataframe with "point_position" and "seg_row" indicating the points fall into which segmentation.
Usage:
CheckPoint(pos, start, end)
Arguments:
pos: a vector of numbers of points
start: a vector of numbers of starting position
end: a vector of numbers of ending positioni
matchAll: logical "T" or "F", default = "T"
Examples:
aa <- c(3,9,21,11)
bb1 <- c(1,8,16)
bb2 <- c(10,15,18)
# find all possible match
CheckMatch(aa,bb1,bb2)
## point_position seg_row
# 1 1 1
# 2 2 1
# 3 2 2
# 4 4 2
## 1st point within 1st segment; 2nd points within 1st and 2nd segment;
## 4th point in 2nd segment.
# find the first match line and break
CheckMatch(aa,bb1,bb2,matchAll='F')
## point_position seg_row
# 1 1 1
# 2 2 1
# 3 4 2
## 1st point FIRST match in 1st segment; 2nd point FIRST match 1st segment
## 4th point FIRST match in 2nd segment.
======================================================
check segments overlap with other segments
Description:
To check if a segments overlap with other segments.
Usage:
CheckRange2Range(aa_start,aa_end,bb_start,bb_end)
Arguments:
aa_start: a vector of numbers of starting positions of checked segments
aa_end: a vector of numbers of ending position of checked segments
bb_start: a vector of numbers of starting position of other segments
bb_end: a vector of numbers of ending position of other segments
Examples:
aa_start <- c(2,6,11)
aa_end <- c(4,9,15)
bb_start <- c(1,5,7)
bb_end <- c(3,8,10)
# to see if segments 2-4,6-9,11-15 overlap with 1-3,5-8,7-10
CheckRange2Range(aa_start,aa_end,bb_start,bb_end)
