compare(c(1, NA, 2), c(1, 2))
Output
`old`: 1 NA 2
`new`: 1 2
Code
compare(c(1, 2, NA), c(1, 2))
Output
`old`: 1 2 NA
`new`: 1 2
informative difference between NA and NaN when tolerance set
Code
compare_numeric(NA_real_, NaN)
Output
v No differences
Code
compare_numeric(NA_real_, NaN, tolerance = NULL)
Output
`x`: NA
`y`: NaN
numeric comparison works on factors
Code
f1 <- factor(c("a", "b", "c"))
f2 <- factor(c("a", "c", "b"), c("a", "c", "b"))
compare(f1, f2)
Output
`levels(old)`: "a" "b" "c"
`levels(new)`: "a" "c" "b"
Code
f3 <- factor(c("a", "B", "c"))
compare(f1, f3)
Output
`levels(old)`: "a" "b" "c"
`levels(new)`: "B" "a" "c"
`old`: "a" "b" "c"
`new`: "a" "B" "c"
shows row-by-row diff for numeric matrices
Code
x <- y <- matrix(1:4, nrow = 2)
y[2, 2] <- 5L
compare(x, y)
Output
old vs new
[,1] [,2]
old[1, ] 1 3
- old[2, ] 2 4
+ new[2, ] 2 5
but not for arrays
Code
x <- y <- array(1:4, c(1, 2, 2))
y[1, 2, 2] <- 5L
compare(x, y)
Output
`old`: 1 2 3 4
`new`: 1 2 3 5
falls back to regular display if printed representation the same
Code
x <- y <- matrix(1:4, nrow = 2)
y[2, 2] <- y[2, 2] + 1e-10
compare(x, y)
Output
`old` is an integer vector (1, 2, 3, 4)
`new` is a double vector (1, 2, 3, 4.0000000001)
uses format method if available
Code
compare(structure(1, class = "Date"), structure(1.5, class = "Date"))
Output
`unclass(old)`: 1.0
`unclass(new)`: 1.5
Code
compare(structure(1, class = "Date"), structure(100, class = "Date"))
Output
`old`: "1970-01-02"
`new`: "1970-04-11"
Code
compare(.POSIXct(1, "UTC"), .POSIXct(2, "UTC"))
Output
`old`: "1970-01-01 00:00:01"
`new`: "1970-01-01 00:00:02"
Code
compare(factor("a"), factor("b"))
Output
`levels(old)`: "a"
`levels(new)`: "b"
Code
compare(ordered("a"), ordered("b"))
Output
`levels(old)`: "a"
`levels(new)`: "b"
Code
compare(factor(c("a", "b")), factor(c("a", "b"), levels = c("b", "a")))
Output
`levels(old)`: "a" "b"
`levels(new)`: "b" "a"
`unclass(old)`: 1 2
`unclass(new)`: 2 1
ignore_attr never uses format method
Code
compare(.POSIXct(1, "UTC"), .POSIXct(2, "UTC"), ignore_attr = TRUE)
Output
`old`: 1
`new`: 2
don't use format if numeric & within tolerance
Code
compare(dt, dt + 5)
Output
`old`: "2016-07-18 16:06:00"
`new`: "2016-07-18 16:06:05"
Code
compare(dt, dt + 5, tolerance = 1e-08)
Output
v No differences
can compare complex numbers
Code
compare(1:2 + 0+1i, 2 + 0+1i)
Output
`old`: 1+1i 2+1i
`new`: 2+1i
Code
compare(1:2 + 0+1i, 1:2 + 0+2i)
Output
`Im(old)`: 1 1
`Im(new)`: 2 2
logical comparisons minimise extraneous diffs
Code
compare_logical(x1, x2)
Output
`x[1:4]`: TRUE TRUE TRUE TRUE
`y[1:4]`: FALSE TRUE TRUE TRUE
`x[22:28]`: TRUE TRUE TRUE TRUE TRUE TRUE TRUE
`y[22:28]`: TRUE TRUE TRUE FALSE TRUE TRUE TRUE
`x[47:50]`: TRUE TRUE TRUE TRUE
`y[47:50]`: TRUE TRUE TRUE FALSE
Code
compare_logical(x3, x4)
Output
`x[1:3]`: TRUE FALSE TRUE
`y[1:4]`: FALSE TRUE FALSE TRUE
`x[48:50]`: FALSE TRUE FALSE
`y[49:52]`: FALSE TRUE FALSE TRUE
