Hi there, I have a problem about lapply, strsplit, and accessing list elements, which I don't understand or cannot solve:
I have e.g. a character vector with three elements: x = c("349/077,349/074,349/100,349/117", "340/384.2,340/513,367/139,455/128,D13/168", "600/437,128/903,128/904") The task I want to perform, is to generate a list, comprising the portion in front of the "/" of each element of x: neededResult = list(c("349","349", "349", "349"), c("340", "340", "367", "455", "D13"), c("600", "128", "128") ) I figured out that for a single element of x the following works unlist( lapply( strsplit( unlist( strsplit(x[1], "\\,") ), "/"), "[", 1) ) but due to "unlist" it doesn't provide the required result if extended to all elements of x unlist(lapply(strsplit( unlist( lapply(x, strsplit, "\\,")), "/"), "[",)) Someone can help me to get the needed result?
