output, the NA are supposed to be the second item in the Header. Is there
any way to Import more than one row as headers?. Thank you

read.xls in the development version of the gdata package can read xls
and xlsx files and could interpret both header rows by reading the
file twice. Using the ExampleExcelFile.xlsx file that comes with gdata
assume that the first two rows are actually headers (so the row of 1s

I am new to mmlcr and am working on a latent class mixture model attempting
to identify
the trajectory and number of classes that best describes my data. I am able
to find model
parameters such as degrees of freedom, loglikelihood, and BIC.
For example, here is a cubic 3-class model I am using.
Try this:
a - b - read.table(textConnection(
1 + name1 1 2 3
2 + name2 5 9 10
2 - name3 56 74 93
1 - name4 65 75 98), skip=1, header=FALSE)
swapidx - with(a, (V1 == 2 V2 == +) | (V1 == 1 V2 == -))
b[swapidx,] - b[swapidx, c(1:3,6:4)]
This creates an indexing vector that identifies which rows
1 - 100 of 115 matches
