This article mainly introduces the R language how to detect whether there is Inf/Inf NA NaN related knowledge, the content is detailed and easy to understand, the operation is simple and fast, has a certain reference value, I believe you will gain something after reading this R language how to detect whether there is Inf/Inf NA NaN article, let's take a look.

The data in R sometimes have the situation of NA (missing) NaN (not number)-Inf/Inf (infinity) that affects the calculation. Checking whether this situation occurs in the data can be judged by is.na or is.nan, and is.finite () or is.infinite ().

Data Data

> Data [1] 1 2 3 NA-Inf Inf 4 5 NaN

For example, is.na can determine whether NA or NaN is missing:

> is.na (Data) [1] FALSE FALSE FALSE TRUE FALSE FALSE FALSE FALSE TRUE > data [is.na (Data)] [1] NA NaN

For example: the case of is.nan NaN:

> is.nan (Data) [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE FALSE TRUE > data [is.nan (Data)] [1] NaN

Is.finite () or is.infinite () determines whether it is infinite:

> data [is.finite (Data)] [1] 12345 > is.infinite (Data) [1] FALSE FALSE FALSE FALSE TRUE TRUE FALSE FALSE FALSE > data [is.detection (Data)] [1]-Inf Inf's article on "how to detect Inf/Inf NA NaN in R language" ends here.
