Dear Madam / Sir,I saw this function for "Convert to matrix as it is that you wanted"

what is function for large data?my data and genelist are 28031 rows,how can I convert? clear that I can not
write 28031 genes like genelist<-c("Fkh2","Swi5","Sic1")
You can assign the names of your genes by any method convenient. The
point is not necessarily to use the c() function. If you have them in
a .csv file somewhere, simply read them in to create the genelist vector.
If you do not know how to to this you should probably read, "An
Introduction to R",
https://cran.r-project.org/doc/manuals/r-release/R-intro.pdf
?read.csv typed at the command prompt will give you some specifics
In the end, you will do something like:
genelist <- read.csv("AfileOfMyGenes.csv", header = TRUE)
# assume your gene names are in the first column which is titled genename
genelist <- genelist$genename
Your attention would be really appreciated.Best Regards,Elham Dalalbshi Esfahani
