Hi, I'm a beginner with Bioconductor packages. I have a data frame (365000*355) with beta mesures of dna methylation. The dimnames of my data are CpG names on lines and ids on colonnes. So I extract the names of CpG sites (ex : "cg00000029" "cg00000109" "cg00000165" "cg00000236" "cg00000289") and I would like to get their genomic coordinates in R. If I search the CpG's name on UCSC Genome Browser on Human (GRCh37/hg19), I can get the name of Chromosome and the genomic position( Example cg00000029 : chromosome ch16; genomic position 53,468,112). But I cannot search manually all the CpG's genomic coordinates on the UCSC Genome Browser on Human (GRCh37/hg19). I will take too long. Do you know a R function of bioconductor package that I can use to solve my problem? Thank you very much. Code should be placed in three backticks as shown below
# include your problematic code here with any corresponding output
# please also include the results of running the following in an R session

Thank for your response. It is Illumina 450 K. I use this code
```{r }
annotation <- getAnnotation(IlluminaHumanMethylation450kanno.ilmn12.hg19)
```
