...l date en ambos dataframe tiene el formato dmy_hms. Los dataframe tienen diferente número de filas. dataframe contaminantes contiene 175247 filas y el dataframe meteorología 175321. Quiero saber cuáles son los valores de la variable date que son distintos en ambos dataframe. He usado la función anti_join de dplyr dándome el siguiente error anti_join(meteorologia$date,contaminantes$date) Error in UseMethod("anti_join") : no applicable method for 'anti_join' applied to an object of class "c('POSIXct', 'POSIXt')" También he empleado el paquete sqldf...

The anti_join from the package dplyr might also be handy. install.package("dplyr") library(dplyr) anti_join (x1, x2) You can get help on the different functions by ?function.name(), so ?anti_join() will bring you help - and examples - on the anti_join function. It might be worth testing your approac...

...nta es, ¿incluiríais estas palabras que me aparecen en todos los topics o casi todos como stopwords? ¿Hay alguna forma de refinar más el análisis y que haya más diferencias entre topics? Este es el código que estoy usando: Reviews_dtm <-text_df12star %>% unnest_tokens(word, text) %>% anti_join(stop_words)%>% count(Brand, word) %>% cast_dtm(Brand, word, n) Reviews_lda <- LDA(Reviews12_dtm, k = 15, control = list(seed = 2016)) Un saludo Miriam

Cool, looks like that'd do it, almost as if converting an entire record to a character string and comparing strings. -- M. B. Hardy, statistician work: Applied Research Associates, S. E.

Buenas, Estoy analizando texto en R y no encuentro cómo eliminar los números y símbolos del texto como ",", "%", etc. Estoy pasando este código, text_data es donde está el texto en la variable "text". tidy_data <- text_data%>% unnest_tokens(word, text)%>% anti_join(stop_words) ¿Cómo podría añadirse a ese código? Muchas gracias

Hi, I'll coded your example into R code: Table_A <- c('abc at gmail.com', 'John Chan', '0909') Table_A <- rbind(Table_A, c('bcd at yahoo.com', 'Tim Ma', '89089')) colnames(Table_A) <- c('Email', 'Name', 'Phone') Table_A Table_B <- c('abc at gmail.com', 'John Chan', 'M',

If your two objects have class "data.frame" (look at class(objectName)) and they both have the same number of columns and the same order of columns and the column types match closely enough (use all.equal(x1, x2) for that), then you can try which( rowSums( x1 != x2 ) > 0) E.g., > x1 <- data.frame(X=1:5, Y=rep(c("A","B"),c(3,2))) > x2 <-

Thanks - Peter, Eivind, Rui Sorry, I perhaps could not explain it properly in the first go. Trying to simplify it here with an example - Say I have two dataframes as below that are NOT equally-sized data frames (i.e., number of columns are different in each table): Table_A: Email Name Phone abc at gmail.com John Chan 0909 bcd at yahoo.com Tim Ma
