center.............. (v) width center text
form: width center text
clipfmt............. (v) format data for clipboard
format array of rank 0 1 or 2 for clipboard.
columns are separated by TAB, rows by CRLF.
clipunfmt........... (v) unformat data read from clipboard
returns boxed matrix from clipboard result,
recognizing TAB and CRLF as separators.
characters are not converted to numbers.
note this is not a true inverse of clipfmt.
e.g. try: clipunfmt clipfmt i.5 6
colhdr.............. (v) column headers
returns matrix of column headers.
y. = list with columns delimited by semicolons; and lines
in each column delimited by commas.
x. is wid or (wid;just), where:
wid = column widths
just = a singleton or vector of:
0 = centre header, then right justify (default)
1 = center header in wid
2 = right justify
3 = left justify
e.g. hdr=. 'Number,of,employees;Total,salary;Monthly,net,payment'
(15 12 12;1) colhdr hdr
expandby............ (v) expand data with fit value
e.g. 0 1 0 0 1 expandby 99 [ 10 20
99 10 99 99 20
expandn............. (v) expand data at every nth item
n expandn dat
expand array at every nth cell.
e.g. 'ABC DEF G' = 3 expandn 'ABCDEFG'
flatten............. (v) flatten array to a character string
flattens array to a character string with same display
useful for printing arrays of rank > 1
fmt................. (v) format numeric matrix, various options
syntax: specs fmt nums
nums = numeric vector or matrix or boxed list
a vector is treated as a 1-row matrix.
a boxed list is treated as boxed columns
specs= formats, separated by commas, applied
to each column, or item if boxed.
formats are either edit or positional:
edit formats have the form: {o}w{.d}, where:
o is optional qualifiers from the set:
nr=n repetitions (must be given first)
b=blank if zero
c=commas
z=zero fill
w is field width
d is decimal places
positional formats have the form:
xn = n blanks, e.g. x3
e.g. 'c10.3,x2,2rz5' has formats:
width 10, decimal places 3, commas
2 blanks
width 5, zero fill, repeated twice
fold................ (v) fold text to width
syntax: {width} fold data
data is character vector
width defaults to screenwidth
hexdump............. (v) show text as hex and ascii characters
nfmt................ (v) simple numeric formatter
simple format of numeric vector or matrix in readable form.
opt is optional, up to 3 elements:
0 = maximum decimal places, max 9 (4)
1 = minimum field width (0)
2 = display width (screenwidth)
ruler............... (v) returns formatted ruler
returns a formatted ruler
e.g. ruler 75 horizontal
1 ruler 30 vertical
sqzint.............. (v) squeeze list of positive integers into short form
Squeeze list of positive integers into short character list.
If x. = 1, sort y. first.
e.g. sqzint 1 2 3 7 8 9 10 = 1-3,7-10
see also <sqzrun>
sqzrun.............. (v) squeeze list of numbers into short form
Squeeze list of numbers into short character list.
e.g. sqzrun 1.1 1.1 1.1 7 9 9 10.25 = 3#1.1,7,2#9,10.25
See also <sqzint>.
xfmt................ (v) format extended integers
form: [width] xfmt number
groups in 3's up to 1e12, and 5's thereafter
