I tried the following way:

 melipona <- paste(system.file(package="dismo"), "/ex/Melipona.csv", sep=";")


 melipona<-read.csv(melipona,header=TRUE,sep=";")

Answer 1

The archive Melipona.csv is not located in the directory C:/Users/N1na3/Documents/R/win-library/3.4/dismo/ex/. I listed the contents of this directory on my computer and there are only two . csv files, called acaule.csv and bradypus.csv.

$ ls /Library/Frameworks/R.framework/Versions/3.4/Resources/library/dismo/ex/

Since I don’t have access to your computer, I can only speculate on a possible solution to your problem. Do the following:

1) Copy the file Melipona.csv somewhere known inside your computer. For example, a folder like Documents/Dissertation/Melipona/Analyze/

2) Inside Rstudio, go to the menu Session > Set Working Directory > Choose Directory . Navigate to the directory where the file Melipona.csv is stored.

3) Turn the remote

melipona <- read.csv("Melipona.csv", header=TRUE, sep=";")

This should complete the reading of your file without major problems.

Answer 2

Run the command again:

Melipona <- read.csv(Melipona, header=TRUE,Sep=";")

Only this time try:

 melipona <- read.csv('melipona.csv', header=TRUE, sep=";")

I have that problem sometimes.
