I would try write.csv or write.table with row.names = FALSE - just a guess, and do follow up on R-Sig-Geo if need be.

[R] Mysterious issues with reading text files from R in ArcGIS and Excel
It seems within the last ~3 months Ive been having issues with writing text or csv files from a R data frame. The problem is multifold and it is hard to filter out what is going on and where the problem is. So, Im hoping someone else has come across this and may provide insight. My current settings for R: R version 2.15.2 (2012-10-26) Platform: x86_64-w64-mingw32/x64 (64-bit) locale: [1] LC_COLLATE=Swedish_Sweden.1252 LC_CTYPE=Swedish_Sweden.1252 LC_MONETARY=Swedish_Sweden.1252 LC_NUMERIC=C [5] LC_TIME=Swedish_Sweden.1252 attached base packages: [1] tcltk stats graphics grDevices utils datasets methods base other attached packages: [1] adehabitat_1.8.11 shapefiles_0.6 foreign_0.8-51 tkrplot_0.0-23 ade4_1.5-1 loaded via a namespace (and not attached): [1] tools_2.15.2 I am using Microsoft Excel 2010 and ArcGIS 10.1sp1 for Desktop Basically, no matter what data frame I am working on, when I export it to a text file to be use in Excel or ArcGIS problems arise. Im not sure if it is R or these other programs, maybe forums for ArcGIS might be more appropriate, but this problem only occurs when I use tables that have been produced from an R session. When I try to open a text file in Excel, either I get an error message stating The file you are trying to open is in a different format than specified by the file extension. Verify that the file is not corrupted and is from a trusted source. Followed by Excel has detected that 'file.txt' is a SYLK file, but cannot load it. Either the file has errors or is not a SYLK file format. Click OK to open the file in a different format Then the file opens Otherwise, the file opens fine the first time through - and looks ok. I can't figure out what Im doing different between the two commands of write.table as they are always written the same: write.csv(file, file = D:/mylocations/fileofinterest.csv) or write.table(file, file = D:/mylocations/fileofinterest.txt) Sometimes I will try to add sep = , or sep = ; but these don't make a difference (which I didn't figure they would). The other program I use is ArcGIS and bringing in a txt file from R is really messing things up as 2 new columns of information are typically added and date/time data is usually lost with txt files, but not with csv files. For instance - a text file that looks like this in Excel: id x y date R1dmed R1dmean R1error R2error 1 F07001 1482445 6621768 2007-03-05 10:00:53 2498.2973 2498.2973 FALSE FALSE 2 F07001 1481274 6619628 2007-03-05 12:00:41 657.1029 657.1029 FALSE FALSE 3 F07001 1481279 6619630 2007-03-05 14:01:12 660.3569 660.3569 FALSE FALSE 4 F07001 1481271 6619700 2007-03-05 16:00:39 620.1397 620.1397 FALSE FALSE in ArcGIS now looks like this: Field1idid_Xid_YxydateR1dmedR1dmean R1errorR2errorOBJECTID * 1F07001118.0818119.485541e+01514824456621768NA2498.297272498.29727FALSEFALSE1 2F07001118.0818119.485541e+01514812746619628NA657.102922657.102922FALSEFALSE2 3F07001118.0818119.485541e+01514812796619630NA660.356911660.356911FALSEFALSE3 4F07001118.0818119.485541e+01514812716619700NA620.139702620.139702FALSEFALSE4 5F07001118.0818119.485541e+01514808496620321NA378.186792378.186792FALSEFALSE5 Where did id_X and id_Y come from??

Since it also has blanks in the formatted POSIXct column, you're very likely to run into problems reading it. Use write.csv(test, test.csv) and you'll have fewer problems. If you want tab-delimited columns instead, you'll need to specify that in the write.table call.

Re: [R] Mysterious issues with reading text files from R in ArcGIS and Excel
I realize my command code is not writing a CSV file, I already pointed out that CSV file seems to work OK but not in the TXT format. Regardless of that, there should be no problems in ArcGIS in reading the date column - in ArcGIS it will simply recognize it as a text field by default. As I said in my initial posting, when I use other programs to create a text file (say textpad,wordpad, notepad or excel) and bring the txt file into ArcGIS, there is no dropping of the information - it doesn't turn the column into NA's. It only does this when I try to add text files that were generated from using the write.table or write.csv. Any thoughts at to explain why I get 2 new columns of data in either the CSV format or the TXT format? ~K On 04/03/2013 10:52 AM, Kerry wrote: Here's the first 5 lines of my dataset: structure(list(id = structure(c(1L, 1L, 1L, 1L, 1L), .Label = c(F07001, F07002, F07003, F07004, F07005, F07006, F07008, F07009, F07010, F07011, F07014, F07015, F07017, F07018, F07019, F07020, F07021, F07022, F07023, F07024, F10001, F10002, F10004, F10008, F10009, F10010, F10012, F10013, F10014, F98015, M07007, M07012, M07013, M07016, M10007, M10011, M10015), class = factor), x = c(1482445L, 1481274L, 1481279L, 1481271L, 1480849L), y = c(6621768L, 6619628L, 6619630L, 6619700L, 6620321L), date = structure(c(1173085253, 1173092441, 1173099672, 1173106839, 1173114055), class = c(POSIXct, POSIXt), tzone = ), R1dmed = c(2498.29727014221, 657.102921923195, 660.356911071581, 620.139702002702, 378.186792471657), R1dmean = c(2498.29727014221, 657.102921923195, 660.356911071581, 620.139702002702, 378.186792471657 ), R1error = c(FALSE, FALSE, FALSE, FALSE, FALSE), R2error = c(FALSE, FALSE, FALSE, FALSE, FALSE)), .Names = c(id, x, y, date, R1dmed, R1dmean, R1error, R2error), row.names = c(NA, 5L), class = data.frame) and here's the code I wrote for this file: write.table(test, D:/MooseEncounters/locations/Individual/test.txt) That's not a CSV file, it is being written with a blank as separator.

Re: [R] Mysterious issues with reading text files from R in ArcGIS and Excel
Your description of diagnosis uses non-R software (off topic here). Please either describe the difference in the files (you may need a hex editor or the hexbin package to detect the differences) or supply the files that behave differently (this may require some alternate route than this mailing list if there are odd characters at fault). For what it is worth, TXT is not a clearly-defined format, so this could be more effectively addressed by using a more specific format for data exchange. --- Jeff NewmillerThe . . Go Live...
