[R] Output for pasting multiple vectors

[Spencer Brackett]

The following is what I have implemented thus far...

The file object for the two files listed in lines 1-2 was set in my working
directory, and are under the folder "Vakul's GBM Code"... hence the source
of the odd 'prefix' for .txt files shown

>library(data.table)>.anno = as.data.frame(fread(file = "~Vakul's GBM
Code/mapper.txt", sep ="\t", header = T))
>meth = read.table(file = "~Vakul's GBM Code/GBM.txt", sep  ="\t", header =
T, row.names = 1)
>meth = as.matrix(meth)

##  the loop just formats the methylation column names to match format ##
colnames(meth) = sapply(colnames(meth), function(i){
  c1 = strsplit(i,split ='\\', fixed = T)[[1]]
  c1[4] = paste(strsplit(c1[4],split = "",fixed = T)[[1]][1:2],collapse =
 "")
  paste(c1,collapse = ".")

Rendering reprex...
Error in parse(text = x, keep.source = TRUE) :
  <text>:28:0: unexpected end of input

Best,

Spencer
