I am working on Rstudio, whenever I put a code is giving me an error, what might be the reason.

> source("http://bioconductor.org/biocLite.R") > biocLite("SRAdb") > library(SRAdb) > sqlFile sraCon install.packages("R.utils") > library(R.utils) > download.file(url="ftp://ftp.ddbj.nig.ac.jp/ddbj_database/dra/fastq/SRR926846/SRR926845.fastq.bz2") > bunzip2(list.files(pattern = ".fastq.bz2$")) > source("http://bioconductor.org/biocLite.R") > biocLite("ShortRead") > library(ShortRead)

these are my codes, I want to run them in R studio, put I could not. these codes are only to pring accession number from the SRA database, and the configure it to certain file type to start the gene expression analysis.

Also, I deleted files from my desktop through R, how can I retraive them.
