Error In Data.frame Duplicate Row.names

Row numbers (or row indices) are simply the consecutive sequence of integers from 1 to nrow(df). In other words, > paste (c("ML1,ML32,ML4,ML29,etc"), sep="") [1] "ML1,ML32,ML4,ML29,etc" is a character vector of length one, so you cannot set the column names for a 44 column matrix using that command. Unfortunately, there are some R packages on CRAN that explicitly use the row names which often creates problems. I have a data frame named x x dimensions ar... More about the author

It IS providing row names for a matrix. It is populated with alphanumeric identifiers... I'm tryin... Usually, row names appear to be the same as row numbers but this is not the case.

Everything work fine, except when I want to had the name of the genes as the row.names with >row.names (a)<-a$Name And there's this things that duplicate are not allowed... It is easy to confuse row numbers for row names and vice versa. We want to know various things about the dataframe such as how many rows and columns it has.

Make sure that the vector you want to assign to the row names has exactly as many elements as the data.frame has rows, and that all elements in the vector are The kind of indexing used depends on the type of index. It depends on the type of NA. > df[NA, ] speed dist NA NA NA NA.1 NA

What if my company didn't pay the recruiter? my review here If you're not sure whether or not you have duplicates, try running this code: length(unique(Data[,1]))==length(Data[,1]) Output of "[1] FALSE" indicates that you have at least one duplicate.

Avoid the use of row names.

If you're doing that then you're doing something completely wrong and not understanding how R works. Huh? ADD COMMENT • link written 20 months ago by James W. navigate to this website Any other ideas?
