Function to export workspace objects(data frames) to csv files

Question

I want to batch export data frames in my workspace having the string "obj" in their names to a csv file with the same name

I thought of the following code, which unfortunately does not work.

for (i in ls(pattern="obj")){
write.csv2(i, paste(i,".csv", sep=""))
}

Any ideas? Thank you in advance

Answer 1

write.csv2 takes the object rather than the name of the object as its first argument. Use get to remedy this.

write.csv2(get(i), paste(i,".csv", sep=""))

Answer 2

You can do it with eval:

eval(call("write.csv2", as.name(i), paste(i, ".csv", sep="")))
