pattern_weave() returns a logical matrix indicating where the warp lines should
be "up" for a specified weave pattern type and subtype.
names_weave is a character vector listing supported weave pattern types.
pattern_weave(type = "plain", subtype = NULL, nrow = 5L, ncol = 5L)names_weave
A matrix of logical values indicating where the "warp"
is "up" (if TRUE) or "down" (if FALSE).
Indices [1,1] of the matrix corresponds to the bottom-left of the weave
while indices [1,ncol] corresponds to the bottom-right of the weave.
This matrix has a "pattern_weave" subclass which supports a special print() method.
An object of class character of length 10.
Type of weave. See Details.
Subtype of weave. See Details.
Number of rows (length of warp).
Number of columns (length of weft).
Here is a list of the various weave types supported:
A simple criss-cross pattern using two threads at a time.
Same as the "matt_irregular" weave but with a default subtype of 2L.
A simple criss-cross pattern using 3 (or more) threads at a time.
Same as the "matt_irregular" weave but with a default subtype of 3L.
A generalization of the "plain" weave.
A character subtype "U/D(L+R)" is a standard matt weave specification:
U indicates number warp up, D indicates number warp down,
L indicates number of warp up in repeat, and
R indicates number of warp down in repeat.
An integer subtype N will be interpreted as a "N/N(N+N)" irregular matt weave.
A character subtype "U/D" will be interpreted as a "U/D(U+D)" irregular matt weave.
Has a default subtype of "3/2(4+2)".
A simple criss-cross pattern.
Same as the "matt_irregular" weave but with a default subtype of 1L.
A plain weave variation that emphasizes vertical lines.
An integer subtype N will be interpreted as a "matt_irregular" "N/N(1+1)" weave.
A character subtype "U/D" will be interpreted as a "matt_irregular" "U/D(1+1)" weave.
Default subtype of 2L.
A "regular" satin weave is a special type of the elongated twill weave
with a move number carefully chosen so no twill line is distinguishable.
Same as the "twill_elongated" weave but with a default subtype of 5L.
A simple diagonal pattern.
Same as the "twill_elongated" weave but with a default subtype of "2/1".
A generalization of the "twill" weave.
A character subtype "U/D(M)" is a standard twill weave specification:
U indicates number warp up, D indicates number warp down,
and M indicates the "move" number.
A character subtype "U/D" will be interpreted as a "U/D(1)" elongated twill weave.
An integer subtype N will provide a "{N-1}/1(1)" elongated twill weave
if N is less than 5, 6, or greater than 14 otherwise it will
provide a "{N-1}/1(M)" weave where M is the largest
possible regular "satin" move number.
Default subtype of "4/3(2)".
Adds a (vertical) "herringbone" effect to
the specified "twill_elongated" weave.
Default subtype of "4/3(2)".
Adds a (vertical) "zig-zag" effect to the specified "twill_elongated" weave.
Default subtype of "4/3(2)".
For both "matt" and "twill" weaves the U/D part of the subtype can be further extended
to U1/D1*U2/D2, U1/D1*U2/D2*U3/D3, etc.
For the "matt" weave the "(L+R)" part of the subtype can be further extended
to (L1+R1+L2+R2), (L1+R1+L2+R2+L3+R3), etc.
