R Question

I'm trying to sum a vector of doubles in a data frame. When the sum is relatively low, this works as intended.

`df <- data.frame(`

numbers = c(50, 632.5, 12.45)

)

sum(df$numbers)

# 694.95

But when the sum gets higher, the R begins to round the sum.

`df <- data.frame(`

numbers = c(50000000, 632.5, 12.45)

)

sum(df$numbers)

# 50000645

How can I stop R from eliminating these decimal points? The output I want is:

`sum(df$numbers)`

# 50000645.95

Answer

Try setting the number of digits in options, you can set whatever works for you. For example:

```
options(digits = 10)
sum(df$numbers)
[1] 50000644.95
```
