I have a question that I don't have a good answer for (note the word "good"; I have an answer, but I consider it not "good"). Take the following data in a single tab-delimited text file:
<text>
A Labels Value SE 2.5% 97.5% R90 0.231787 1.148044 0.035074 1.531779 R0 0.500861 0.604406 0.185336 1.353552
B Labels Value SE 2.5% 97.5% (Intercept) 1.367514 0.036431 1.287975 1.451964 </text>
(Note: the <text> tags are not present and are added here only to show blank lines.)
I would like to read the data into a single data.frame which looks like
Labels Value SE 2.5% 97.5% A.R90 0.231787 1.148044 0.035074 1.531779 A.R0 0.500861 0.604406 0.185336 1.353552 B.(Intercept) 1.367514 0.036431 1.287975 1.451964
A few rules:
1. the number of rows in "A" and "B" will vary from 1 to ???. Here "A" has 1 row (excluding header) and B has 2 rows (excluding header).
2. the number of columns in "A" and "B" will always be the same.
4. the headers for "A" and "B" will always be the same.
3. there is always an empty line at the beginning of the file and in between "A" and "B".
My solution involves scan and indexing though it is error prone and not flexible if more or less than 5 columns are present in the data. While the number of columns is always the same from "A" to "B" it may change that "A" and "B" have more or fewer columns.
I hope this makes sense.
Thanks,
