Invalid 'row.names' length

r

Solution

The "id" argument of seqdef should be a vector containing one entry per sequences (ie. The length of id vector should equal the number of sequences). Try using id=as.character(sample$pid). You can also try id=sample$pid (without as.character)

sample.sts <- seqdef(sample, var=c("jan2005", "feb2005", "mar2005", "apr2005", "may2005", "jun2005", "jul2005", "aug2005", "sep2005", "oct2005", "nov2005", "dec2005", "jan2006", "feb2006", "mar2006", "apr2006", "may2006",  "jun2006", "jul2006", "aug2006", "sep2006", "oct2006", "nov2006", "dec2006",  "jan2007", "feb2007", "mar2007", "apr2007", "may2007",  "jun2007", "jul2007", "aug2007", "sep2007", "oct2007", "nov2007", "dec2007", "jan2008", "feb2008", "mar2008", "apr2008", "may2008", "jun2008", "jul2008", "aug2008", "sep2008", "oct2008", "nov2008", "dec2008"),  alphabet=c("Employee (full-time)", "Employee (part-time)", "Self-employed (full-time)", "Self-employed (part-time)", "unemployed", "Retired", "Student", "Other inactive", "Compulsory military service"), states=c("EF", "EP", "SF", "SP", "UE", "RE", "ST", "IA", "MS"), d=as.character(sample$pid))

There are some mismatch between the states in the data and the alphabet argument since "-" was replaced by ".". You should probably change the alphabet argument (try using seqstatl function to find out, which states labels are present in your data).

Problem

I am trying to use TraMineR's (version 1.8.4) seqdef-funciton to define a sequence object, but I always get this error message which makes no sense to me: Error in `row.names<-.data.frame`(`*tmp*`, value = value) : invalid 'row.names' length My code input is: ``` sample.sts <- seqdef(sample, var=c("jan2005", "feb2005", "mar2005", "apr2005", "may2005", "jun2005", "jul2005", "aug2005", "sep2005", "oct2005", "nov2005", "dec2005"), alphabet=c("Employee (full-time)", "Employee (part-time)", "Self-employed (full-time)", "Self-employed (part-time)", "unemployed", "Retired", "Student", "Other inactive", "Compulsory military service"), states=c("EF", "EP", "SF", "SP", "UE", "RE", "ST", "IA", "MS"), id="pidc") ``` The data frame "sample" looks like this: ``` pidc jan2005 feb2005 ... dec2005 sex edufirst age05 -------------------------------------------------------------------------- 1. 150163920001 . . ... . 1 5 62 2. 211518110003 . . ... . 2 2 17 3. 170295160002 . . ... . 2 1 47 4. 240386550002 2 2 ... 2 2 2 50 5. 320099920001 . . ... . 1 3 38 -------------------------------------------------------------------------- 6. 200167850001 . . ... . 1 5 39 7. 340401190002 6 6 ... 6 1 3 61 8. 180501260002 . . ... . 1 3 29 9. 230083560001 . . ... . 1 3 61 10. 240335270002 3 3 ... 3 2 3 30 ``` The whole output says: [!] found '-' character in states codes, not recommended [>] found missing values ('NA') in sequence data [>] preparing 3266 sequences [>] coding void elements with '%' and missing values with '*' [!] sequence with index: 1,2,3,...

Maybe, someone can help me out and knows what causes this error?
