gantt |
gantt object (from makeGantt). |
a |
element or elements in the gantt chart (character or vector of characters). |
b |
element or elements (character or vector of characters). |
which.a, which.b |
"all": consider all slots of a/b, "first": only consider the first slot of a/b, "last": only consider the last slot of a/b. If which.a/which.b is a number n, the n'th slot is used in the comparison. |
orEqual |
if TRUE, a and b can be at the same time (not just before/after). |
strict |
if FALSE, an element a is considered before/after even though b is not present. |
which |
"all": consider all slots of element, "first": only consider the first slot of element, "last": only consider the last slot of element. If which is a number n, the n'th slot is used in the comparison. |
which.a/which.b |
for isOverlap: any: one or more a/b elements overlap, all: all a/b elements need to overlap, first/first: First a/b needs to overlap, last/last: Last a/b needs to overlap, or use number (or sequence) |
In these functions a and b are compared. Which.a and which.b decides which parts of a an b take part in the comparison. If which.a is "all", all the slots of a are compared to the which.b slots. If which.a is "first", only the first slot of a is considered in the comparison. If which.b is "last", only the last slot of a is considered in the comparison. The same goes for which.b: if b is "all", all slots of b are considered, if b is "first" or "last", only the first/last slot is considered in the comparison. For example, in isBefore, if which.a is "first" and which.b is last, the first slot of a needs to be before the last slot of b.
In practice this means that for isBefore, when a is "all", the last slot of a is compared to b, and when b is "all", the first slot of b i compared to a.
orEqual relaxes the condition of before or after, first or last, so the selected parts of a and b can be overlapping as well. This result in that which.a="all" and orEqual=T means that the last slot are allowed to overlap.
When stict is TRUE, returns 0 when b is not set, when strict is FALSE, a is before b, when b is not set.
