How is Euler's number represented in R? - Quora
Answer (1 of 3): If you are asking how to represent Euler’s number (e) onto the R console, write : exp(1) and enter! It will show you the value, 2.718282. The exp(n) function returns the value e^n! I hope this is the answer you were looking for!

May 15, 2021 -
Hi guys! I just started learning R and I was trying some basic percentage calculations and I don't know why but my RStudio is showing the results like this instead of " 0.00039975146 " as I was expecting.
Does anyone know how to fix this?

Just to extend the other comments that already helped you, I want to mention that this isn't the euler constant. "e" means exponent of 10. This is scientific notation, so basically the number after e tells how many digits the decimal point has been shiftet left or right.

The "e" is a symbol for base-10 scientific notation. The "e" stands for $\times 10^{\rm exponent}$. So -1.861246e-04 means $-1.861246 \times 10^{-4}$. In fixed-point notation that would be -0.0001861246.
This notation is pretty standard. Even Microsoft Excel understands it, not just R.

I cannot yet comment so this answer will be a response to @Mark L. Stone : OP also stated that he's getting covariance matrix values in the scientific notation. Obviously the negative value must be one of the covariances.
To not be completely OT I will just add that working with scientific notation to me looks a bit clunky(especially if you are publishing the results). To supress the notation in R use the command options(scipen=alpha) where alpha is the maximum number of digits for the result to be still expressed in fixed notation.

Hey, i am trying to figure out R for a university project i have to do. I plotted some data with the code plot(variableA~variableB, data=mydata) and it gave me a plot which looks overall good, but instead of using the actual numbers it uses things like „2e+04“ and 8e+04“. I dont want that, how do i change it?

Use GGplot and look into scale_x_continuous and scale_y_continuous. Alternatively you can divide your y or x axis by 100 or 1000 as a factor before putting into the plot to make it more presentable.
