Passing string to file name in R [duplicate]

Question

I have a variable a=0.01

Then I create a matrix: b<-matrix(data=1:5,ncol=5,nrow=1)

I would now like to save the matrix so that the name of the matrix is the value stored in a:

save(b_'string', file="b_'string'.Rdata")

Where 'string' should be the value stored in a, i.e. 0.01

So the file should be called b_0.01.Rdata and the variable stored should be b_0.01

but how about adding 0.01 to the variable name within the file? — user1723765

You need to create a new string to feed to file, e.g. using paste0:

save(b,file=paste0("b_",a,".Rdata"))

You should probably either save 'a' as well to the file, or add 'a' as an attribute to matrix 'b' so you know what it meant.
