How do I set the width of a reprex output?
Say I have a code like this:
(x <- 1:100)
I get this with reprex::reprex(venue = "so")
(x <- 1:100)
#> [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
#> [18] 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34
#> [35] 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51
#> [52] 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68
#> [69] 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85
#> [86] 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100
How can I increase the width of the output to output something like this
[1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50
[51] 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100
One option that I have found but I find rather "un-tidy" is this (include options(width = ...) at the top of the code. But I don't want it to show up in the output, I'd prefer setting the width in the reprex-call.
options(width = 205)
(x <- 1:100)
#> [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50
#> [51] 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100
reprex() allows for knitr's opts-chunk, but I can't get it working with reprex::reprex(venue = "so", opts_chunk = list(out.width = 205)) (which might be related to #421 as pointed out here (Long lines of text output))
Any better solutions?
reprex has a syntax for setting these options but not including them in the output markdown (see here for examples). In this case:
reprex({
#+ setup, include = FALSE
options(width=205)
#+ actual-reprex-code
(x <- 1:100)
}, venue = 'so')
outputs your desired format:
(x <- 1:100)
#> [1] 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50
#> [51] 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100
