read.rwl(fname, header=NULL, long=FALSE)
fname |
a character vector giving the file name of the rwl file. |
header |
logical flag indicating whether the file has a header. If NULL then the function will attempt to determine if a header exists |

therefore use negative numbers.If true only the first 7 characters can be
used for series ids. If FALSE then series ids can be up to 8
characters. |
This reads in a standard rwl file as defined according to the standards of the ITRDB at http://www.ncdc.noaa.gov/paleo/treeinfo.html. Despite the standards at the ITRDB, this occasionally fails due to formatting problems.
A data.frame

series ids are the column names and the years are the row names.
