Looking up Gene IDs in R

Hello,
Given a list of gene names, I need to create a table containing the Ensemble ID, chromosome, start, end of that gene.
Example:

##             ens_id        gene            view  chr start   end
## 1: ENSG00000243485 MIR1302-2HG Gene Expression chr1 29553 30267
## 2: ENSG00000237613     FAM138A Gene Expression chr1 36080 36081
## 3: ENSG00000186092       OR4F5 Gene Expression chr1 65418 69055

What command can I use to look up ensemble IDs and start/end locations of genes?

The biomaRt library is great for this.

library("biomaRt")

genes <- c("MIR1302-2HG", "FAM138A", "OR4F5")

ensembl <- useEnsembl("genes", "hsapiens_gene_ensembl")

gene_info <- getBM(
  mart=ensembl,
  attributes=c("ensembl_gene_id", "external_gene_name", "gene_biotype",
    "chromosome_name", "start_position", "end_position", "strand"),
  filters=list(external_gene_name=genes))

> gene_info
  ensembl_gene_id external_gene_name   gene_biotype chromosome_name
1 ENSG00000243485        MIR1302-2HG         lncRNA               1
2 ENSG00000237613            FAM138A         lncRNA               1
3 ENSG00000186092              OR4F5 protein_coding               1
  start_position end_position strand
1          29554        31109      1
2          34554        36081     -1
3          65419        71585      1
