# R Error in do_one(nmeth) : NA/NaN/Inf in foreign function call (arg 1) (2 Examples)

In this post, I’ll show how to deal with the “Error in do_one(nmeth) : NA/NaN/Inf in foreign function call (arg 1)” in the R programming language.

## Creating Example Data

```set.seed(2987465) # Example vector in R my_vec <- as.character(c("aaa", round(runif(100), 2))) head(my_vec) # First values of example vector # [1] "aaa" "0.38" "0.1" "0.06" "0.54" "0.96"```

## Example 1: Replicating the Error Message in do_one(nmeth) : NA/NaN/Inf in foreign function call (arg 1)

```kmeans(my_vec, 3) # kmeans function leads to error # Error in do_one(nmeth) : NA/NaN/Inf in foreign function call (arg 1) # In addition: Warning message: # In storage.mode(x) <- "double" : NAs introduced by coercion```

## Example 2: Solving the Error Message in do_one(nmeth) : NA/NaN/Inf in foreign function call (arg 1)

```my_vec <- as.numeric(my_vec) # Convert vector to numeric # Warning message: # NAs introduced by coercion```
```my_vec <- my_vec[!is.na(my_vec)] # Remove NA values from vector head(my_vec) # Head of updated vector # [1] 0.38 0.10 0.06 0.54 0.96 0.94```
```kmeans(my_vec, 3) # kmeans functions works properly # K-means clustering with 3 clusters of sizes 34, 23, 43 # # Cluster means: # [,1] # 1 0.8200000 # 2 0.1156522 # 3 0.4139535 # # Clustering vector: # [1] 3 2 2 3 1 1 3 1 3 3 1 2 1 1 2 3 1 2 2 3 1 1 2 2 2 3 1 3 2 3 1 1 1 3 3 2 1 2 3 1 1 1 2 2 1 3 3 2 1 3 3 3 3 1 3 1 3 3 2 1 1 3 3 3 1 2 1 1 3 1 3 3 2 1 3 3 2 3 3 3 2 3 3 1 3 3 2 3 1 3 3 2 3 3 1 1 1 3 1 2 # # Within cluster sum of squares by cluster: # [1] 0.5642000 0.1147652 0.4558279 # (between_SS / total_SS = 86.3 %) # # Available components: # # [1] "cluster" "centers" "totss" "withinss" "tot.withinss" "betweenss" "size" "iter" "ifault"```
