Export a list into a CSV or TXT file in R

Question

I m sorry to ask this question  I m very noob with R  I know there is a lot of threads which are related to the very same problem  I understood that we cannot export a table if one of its elements is a list but I didn t manage to solve my problem though  So  I got a list in R and I want to export it into a CSV or TXT file  Here is the error message that I get when I execute this write table command     write table mylist  test txt  sep       Error in  External2 C writetable  x  file  nrow x   p  rnames  sep  eol      unimplemented type  list  in  EncodeElement    Here is the first element of my list     f10010 1  f10010 1 mots   1  X16               ESPRESSO          TDISC             TASSIMO             5  CARTE             NOIRE             A                 LAVAZZA             9  MALONGO           MIO               MODO              123                13  CAPSULES          DOSES             78G               LONG               17  SPRESSO           CAFE              120G              CLASSIC            21  104G              128G              AROMATIQUE        INTENSE            25  112G              156G              520G              5X16               29  PROMO             TRIPACK           X24               126G               33  16                4X16              APPASSIONATAMENTE APPASSIONATEMENTE  37  BRESIL            CAPSUL            COLOMBIE          CORSE              41  CREMOSAMENTE      DELICATI          DELIZIOSAMENTE    DIVINAMENTE        45  DOLCEMENTE        EQI               GRAND             GRANDE             49  GT                GUATEMALA         HAITI             INTENSAMENTE       53  ITALIAN           MAGICAMENTE       MERE              MOKA78G            57  PETITS            PRODUCT           PURSMATIN         RESERVE            61  RISTRETO          SOAVEMENTE        STYLE             X36               64 Levels  104G 112G 120G 123 126G 128G 156G 16 4X16 520G 5X16 78G     X36   f10010 1 nblabel   1  32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32  27  32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32  53  32 32 32 32 32 32 32 32 32 32 32 32 Levels  32   f10010 1 Freq   1  18 16 16 15 14 14  9  9  9  9  9  8  8  8  7  7  7  6  5  5  3  3  3  3  2  2  27   2  2  2  2  2  1  1  1  1  1  1  1  1  1  1  1  1  1  1  1  1  1  1  1  1  1  53   1  1  1  1  1  1  1  1  1  1  1  1   f10010 1 pct   1  0 56250 0 50000 0 50000 0 46875 0 43750 0 43750 0 28125 0 28125 0 28125  10  0 28125 0 28125 0 25000 0 25000 0 25000 0 21875 0 21875 0 21875 0 18750  19  0 15625 0 15625 0 09375 0 09375 0 09375 0 09375 0 06250 0 06250 0 06250  28  0 06250 0 06250 0 06250 0 06250 0 03125 0 03125 0 03125 0 03125 0 03125  37  0 03125 0 03125 0 03125 0 03125 0 03125 0 03125 0 03125 0 03125 0 03125  46  0 03125 0 03125 0 03125 0 03125 0 03125 0 03125 0 03125 0 03125 0 03125  55  0 03125 0 03125 0 03125 0 03125 0 03125 0 03125 0 03125 0 03125 0 03125  64  0 03125   Thank you all for your help in advance

cat capture output print my list   file  test txt     from R  Export and import a list to  txt file https   stackoverflow com users 1855677 42 is the only thing that worked for me  This outputs the list of lists as it is in the text file

You can simply wrap your list as a data frame  data frame is in fact a special kind of list   Here is an example   mylist   list    mylist   a      1 10  mylist   b      letters 1 10  write table as data frame mylist  file  mylist csv   quote F sep     row names F    or alternatively you can use write csv  a wrapper around write table   For the conversion of the list   you can use both as data frame mylist  and data frame mylist    To help in making a reproducible example  you can use functions like dput on your data

So essentially you have a list of lists  with mylist being the name of the main list and the first element being  f10010 1 which is printed out  and which contains 4 more lists    I think the easiest way to do this is to use lapply with the addition of dataframe  assuming that each list inside each element of the main list  like the lists in  f10010 1  has the same length    lapply mylist  function x  write table  data frame x    test csv     append  T  sep          The above will convert   f10010 1 into a dataframe then do the same with every other element and append one below the other in  test csv   You can also type  write table on your console to check what other arguments you need to pass when you write the table to a csv file e g  whether you need row names or column names etc
