error: $ operator is invalid for atomic vectors

In contrast to subsetting with numeric and character vectors, the logical vector used to subset has to be equal to the length of the vector whose elements are extracted, so if a logical vector y is used to subset x, i.e. Vectors can also be subset using a logical vector. The can be used for any list with named elements, and a data frame is a list of named columns. # attempt to select more than one element in vectorIndex Also in addition to above- the is used for data frames, not atomic vectors- so convert to a data frame first (as.ame) 1. If the atomic vector has names (a names attribute), it can be subset using a character vector of names: v <- 1:3 On some occasions, we would like to know, especially, when the length of the vector is large, index of a particular value, if it exists: > v1='c'

Using texreg to export models in a paper-ready wayĪtomic vectors (which excludes lists and expressions, which are also vectors) are subset using the [ operator: # create an example vector.
