我有这个向量（它很大）myvec。我需要在处将它们匹配/并创建另一个结果向量resvector。如何在R中完成这项工作？
myvec<-c("IID:WE:G12D/V/A","GH:SQ:p.R172W/G", "HH:WG:p.S122F/H")
resvector
IID:WE:G12D, IID:WE:G12V,IID:WE:G12A,GH:SQ:p.R172W,GH:SQ:p.R172G,HH:WG:p.S122F,HH:WG:p.S122H
您可以尝试使用strsplit@Tensibai提到的方法：
sp_vec <- strsplit(myvec, "/") # split the element of the vector by "/" : you will get a list where each element is the decomposition (vector) of one element of your vector, according to "/"
ts_vec <- lapply(sp_vec, # for each element of the previous list, do
function(x){
base <- sub("\\w$", "", x[1]) # get the common beginning of the column names (so first item of vector without the last letter)
x[-1] <- paste0(base, x[-1]) # paste this common beginning to the rest of the vector items (so the other letters)
x}) # return the vector
resvector <- unlist(ts_vec) # finally, unlist to get the needed vector
resvector
# [1] "IID:WE:G12D" "IID:WE:G12V" "IID:WE:G12A" "GH:SQ:p.R172W" "GH:SQ:p.R172G" "HH:WG:p.S122F" "HH:WG:p.S122H"
