Data for book
I am pretty new to R and I have tried all of the suggested ways to access the data for the book, but each way has not worked. Is there any other way to access the data?
after correcting downloading and extracting data and when i run this below command, it shows error
what to do in this case?
enhancerFilePath=system.file("extdata",
"subset.enhancers.hg18.bed",
package="compGenomRData")
cpgiFilePath=system.file("extdata",
"subset.cpgi.hg18.bed",
package="compGenomRData")
read enhancer marker BED file
enh.df <- read.table(enhancerFilePath, header = FALSE)
Error in read.table(enhancerFilePath, header = FALSE) :
no lines available in input
In addition: Warning message:
In file(file, "rt") :
file("") only supports open = "w+" and open = "w+b": using the former
Dear Sir,
Thank you very much for making Computational genomics R. I liked it very much and going through all the chapters and exercises. I want to know where can I find the solutions for the exercises mentioned in the book. Kindly guide me. thanks in advance
> library(data.table)
> df.f=d(enhancerFilePath, header = FALSE,data.table=FALSE)
Error in d(enhancerFilePath, header = FALSE, data.table = FALSE) :
could not find function "d"
Function d() is also not available in data.table CRAN package documentation (https://cran.r-project.org/web/packages/data.table/data.table.pdf).
Is it supposed to be, df.f=fread(enhancerFilePath, header = FALSE,data.table=FALSE)?
> head(df.f)

When I tried to install compGenomeRData by using code:
devtools::install_github("compgenomr/compGenomRData")

Hello,
For exercise 12 in section 2.10.3, I need 2 files, rn4.refseq.bed and rn4.refseq2name.txt. However, these are not present in extdata.

Hi there, error when trying to upload data, same issue reported 2 weeks ago

For exercise 6.6.3 question No. 1
you asked to view the promoters for chr20 in the H1.ESC.H3K4me1.chr20.bw
file. But there is no file with that name.
Dear Dr. Alkalin,
I have two problems with your nice book:
devtools::install_github("compgenomr/compGenomRData")
Downloading GitHub repo compgenomr/compGenomRData@HEAD
Error in utils::download.file(url, path, method = method, quiet = quiet, :
download from 'https://api.github.com/repos/compgenomr/compGenomRData/tarball/HEAD' failed
Also tried githubinstall::githubinstall("compgenomr/compGenomRData") which did not work
I would be very grateful if you could tell me how to solve these problems.
Yours sincerely
Gregor
Hi,
I successfully installed the package with the accompanying data and it worked well on my OS (Linux Manjaro).
Still, as it turns out that the uncompressed data are ~ 600MB large, installing git lfs
(Git Large File Storage) before cloning the repository should help to avoid the error message caused by the download of the large files.
I would like to suggest adding these steps to the README:
Install git lfs: sudo apt-get install git-lfs
(Debian-based Linux distros)
Set up git lfs: git lfs install
prior to the git clone/ devtools::install step.
Best,
Lorena
