Dear group,
Here is an object:
z <-
c("LSCPos100415.csv", "LSCPos100416.csv", "LSCPos100419.csv",
"LSCPos100420.csv", "LSCPos100421.csv", "LSCPos100422.csv",
"LSCPos100423.csv",
"LSCPos100426.csv", "LSCPos100427.csv", "LSCPos100428.csv",
"LSCPos100429.csv",
"LSCPos100430.csv", "LSCPos100503.csv", "LSCPos100504.csv",
"LSCPos100505.csv",
"LSCPos100506.csv", "LSCPos100507.csv", "LSCPos100510.csv",
"LSCPos100511.csv",
"LSCPos100512.csv", "LSCPos100513.csv")
I want to keep only the numeric part of each element.
I thought using something like :
>sub("REGEX","",y)
I tried something with " \\D+", but it is not the final result I want
> sub("\\D+","",y)
