[R] Using a text file as a removeWord dictionary in tm_map

Hi list Although this query applies specifically to the tm package, perhaps it's something that others might be able to lend a thought to. Using tm to do some initial text mining, I want to include an external (to R) generated dictionary of words that I want removed from the corpus. I have

Re: [R] Substring replacement in string

Dear Michael I'm not sure how you mean this. Maybe a more general description of my problem is helpful for clarifying. What I have to deal with are truth table output functions that always take, for example, the following form: Delta - (a*B+a*C*d=Y)*(E+e) I.e. these functions will always

Hi Alrik, With the Biostrings/IRanges infrastructure (Bioconductor packages), you can do this with: library(Biostrings) x0 - BString(pmin(pmax(pmin(x1, X2), pmin(X3, X4)) == Y, pmax(Z1, z1))) donttouch_words - c(pmin, pmax) ## Extract the substrings to modify (target substrings).

Re: [R] Substring replacement in string

Dear Gabor, Many thanks. Works like a charm, but I can't get it to work with pmin(pmax(pmin(a,B),pmin(a,C,d))==Y,pmax(E,e)) i.e., with strings where there're no integers following the components in the pmin/pmax functions. Could this be generalized to handle both cases? Best wishes, Alrik

Re: [R] Substring replacement in string

Dear Alrik This may seem a silly suggestion but why not just define new functions PMIN and PMAX to call pmin and pmax. Obviously that does not solve your problem if it is more general than your example. On 28/02/2015 13:16, Alrik Thiem wrote: Dear Gabor, Many thanks. Works like a charm,
