Dear R'helpers, I am reading lines in a .txt file Each line is stocked into a n elements object, as this:
[958] " 422 287 339 31 203 602 547 1026 500 366 346 227" [959] " 410 67 11 220 110 451 562 598 732 163 163 220" [960] " 179 513 95 186 102 595 333 1289 804 210 294 459" [961] " 276 153 307 138 126 233 623 739 521 421 209 75" [962] " 64 392 60 45 332 371 290 887 599 106 62 184" [963] " 171 168 374 43 71 567 1110 799 960 189 339 279" [964] " 151 353 648 150 85 422 883 962 923 296 228 273" [965] " 213 805 403 43 271 445 463 846 1124 345 295 85" [966] " 574 420 200 39 243 187 249 378 714 318 286 114" [967] " 85 73 192 91 146 484 710 782 750 321 261 65" [968] " 53 487 27 76 150 345 663 848 620 192 129 187" [969] " 461 216 8 251 279 558 1012 838 1330 258 138 115" [970] " 53 83 39 298 117 488 880 815 1087 390 266 355" [971] " 225 184 173 121 167 416 411 667 605 172 60 157" [972] " 318 138 552 192 100 461 450 852 190 361 17 192" Now, I would like to determine how many " " (space) there are in each line ... After to have wipes out the extra spaces (double spaces) with data1[i]<-gsub(x=data1[i],pattern=" ",replacement=" ",fixed=FALSE,extended=FALSE) I have attempted with regrexpr, sub, strsplit and many other character fonctions but I could not obtain the number of " " in each line, in order to further do a test on it. The answer may be trivial but at this time I gave up!!
