Dump () function producing truncated output
I would like your help to dump
figure out why the function is truncating long outputs and what can be done to avoid this behavior. By "truncated" I mean that the function displays ...
instead of printing the full representation of the object.
This is a big problem because it makes some packages svSocket
unusable. The package relies entirely on source dumps as a means of dispatching objects between R sessions.
I see this issue on linux platform (x86_64-pc-linux-gnu) but not mac (x86_64-apple-darwin15.6.0) using latest R version (3.4.1)
Here's an example of reproducibility:
x <- as.list(1:200)
dump("x", stdout())
Output:
list(1L, 2L, 3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L, 11L, 12L, 13L,
14L, 15L, 16L, 17L, 18L, 19L, 20L, 21L, 22L, 23L, 24L, 25L,
26L, 27L, 28L, 29L, 30L, 31L, 32L, 33L, 34L, 35L, 36L, 37L,
38L, 39L, 40L, 41L, 42L, 43L, 44L, 45L, 46L, 47L, 48L, 49L,
50L, 51L, 52L, 53L, 54L, 55L, 56L, 57L, 58L, 59L, 60L, 61L,
62L, 63L, 64L, 65L, 66L, 67L, 68L, 69L, 70L, 71L, 72L, 73L,
74L, 75L, 76L, 77L, 78L, 79L, 80L, 81L, 82L, 83L, 84L, 85L,
86L, 87L, 88L, 89L, 90L, 91L, 92L, 93L, 94L, 95L, 96L, 97L,
98L, 99L, 100L, 101L, 102L, 103L, 104L, 105L, 106L, 107L,
108L, 109L, 110L, 111L, 112L, 113L, 114L, 115L, 116L, 117L,

This is most likely because the parameters (deparse.max.lines) were set; as of version R.3.3.2, dump () performs this configuration as it is considered a "dewaxing activity".
As with svSocket, you don't really need to use a dump to transfer data; generally speaking, serialization / non-serialization is preferred for this.
