r - Delete "" from csv values and change column names when writing to a CSV -

-

i'm trying create csv files out of r table. cant understand why values checked "" when use write.csv() function. data looks this:

        sample  sample_name sample_group    pool_id sample_plate    nortum  sentrix_id    sentrix_position  hybnr     1   00_11242    00_24200n2  mutyh   gs0005703-opa   gs0010004-dna   n     1280307   r007_c005   1     2   00_11242    00_24200n2  mutyh   gs0005704-opa   gs0010004-dna   n   1280307 r007_c011   1     3   00_11242    00_24200n2  mutyh   gs0005702-opa   gs0010004-dna   n   1416198 r007_c011   2     4   00_11242    00_24200n2  mutyh   gs0005701-opa   gs0010004-dna   n   1416198 r007_c005   2     5   00_7    00_7t   mutyh   gs0005701-opa   gs0010004-dna   t   1416198 r006_c005   2     6   00_7    00_7t   mutyh   gs0005702-opa   gs0010004-dna   t   1416198 r006_c011   2     7   00_7    00_7t   mutyh   gs0005704-opa   gs0010004-dna   t   1280307 r006_c011   1     8   00_7    00_7t   mutyh   gs0005703-opa   gs0010004-dna   t   1280307 r006_c005   1     9   01_677  01_677n hnpcc_uv    gs0005701-opa   gs0010004-dna   n   1416198 r002_c006   2     10  01_677  01_677n hnpcc_uv    gs0005704-opa   gs0010004-dna   n   1280307

and in output file csv every value looks this:

"100" "r05_80611" "r05_80611n" "na_fam" "gs0005701-opa" "gs0010004-dna" "n" 1416198 "r003_c006" 2

why function putting quotes around values , there way this.

i'm wondering how can change column names when writing csv files since i`m starter i've no clue on how this.

see manual write.table {utils}.

help(write.csv)  write.csv(x, quote = false)

the justification quoting fields default unquoted fields containing commas misinterpreted.

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
