30/10/2019 · An alternative version of base::all.equal(). This function will return TRUE whenever base::all.equal() would return TRUE, however it will also return TRUE in some other cases: If a is given and b is not, TRUE will be returned if all of the elements of a are the same.

How do I check if two objects, e.g. dataframes, are value equal in R? By value equal, I mean the value of each row of each column of one dataframe is equal to the value of the corresponding row and column in the second dataframe.

all.equal(target, current) Check if two objects are equal, or at least very nearly equal. Don’t get tripped up by the argument names, which make it sound like this function is only for a very specific scenario (convergence) when in truth it can be used for a wide variety of scenarios.

23/8/2017 · all.equal has a default tolerance level around 1.5e-8, & differences below this threshold are not reported. This is why all.equal(x, y) returns TRUE, while all(x==y) returns FALSE. This post discusses the issue in more detail: Numeric comparison difficulty in R

25/10/2019 · This function makes a global comparison of two phylogenetic trees. This function is meant to be an adaptation of the generic function all.equal for the comparison of phylogenetic trees.

26/1/2017 · I have faced some strange behavior in the R’s all.equal function. Basically, I create two same data.frames differently and then call the all.equal function (checking data and attributes as well). The code to reproduce the behavior is as follows: var.a <- data.frame(cbind

Hi Laura, You have gotten several good suggestions. Here are two more that may be helpful if you have (or potentially could have) unruly data. In one case, the values are theoretically, but not computationally identical. In the other, missing values lead to NA being

I think I remember reading about both “all.equal” and “identical” in Venables and Ripley (2002) MASS. Unfortunately, I don’t have MASS handy now, and I could not find it otherwise, so I asked. What needs to happen to upgrade the “all.equal” documentation to

In earlier R versions, isTRUE <- function(x) identical(x, TRUE), had the drawback to be false e.g., for x <- c(val = TRUE). Numeric and complex vectors will be coerced to logical values, with zero being false and all non-zero values being true.

(2 replies) Dear all How should one parse all.equal() output? I’m specifically referring to the ‘mean relative difference’ messages. For example, [1] “Mean relative difference: 8.491368e-08” But I’m not sure how to understand these messages. When they’re close to 0
