Olá pessoal, tudo bem ? Estou com um problema, estou querendo fazer o merge entre dois bancos de dados:
dim(bancolink) [1] 1630328 8 dim(fichaAlink) [1] 2954930 6
Minha variável - chave primária está com o formato character. Daí qunado eu faço:
CadUnico_fichaA_merge = merge(bancolink, fichaAlink, by.x=c('CPF'), by.y=c('NUMERO_CPF'))
Error in vecseq(f__, len__, if (allow.cartesian || notjoin || !anyDuplicated(f__, : Join results in 150596694 rows; more than 4585258 = nrow(x)+nrow(i). Check for duplicate key values in i each of which join to the same group in x over and over again. If that's ok, try by=.EACHI to run j for each group to avoid the large allocation. If you are sure you wish to proceed, rerun with allow.cartesian=TRUE. Otherwise, please search for this error message in the FAQ, Wiki, Stack Overflow and datatable-help for advice. Tentei fazer usando o formato data.table, daí ele dá um erro também:
CadfAmerge = bancolink[fichaAlink]
Error in `[.data.table`(bancolink, fichaAlink) : When i is a data.table (or character vector), x must be keyed (i.e. sorted, and, marked as sorted) so data.table knows which columns to join to and take advantage of x being sorted. Call setkey(x,...) first, see ?setkey. Desde já agradeço a todos, -- Wagner S. Tassinari Departamento de Matemática Universidade Federal Rural do Rio de Janeiro.
