## Preserving numeric columns

 Consider the following dataset:  I need to replace NAs with "-" but I lose my numeric formatting  fall.estimate <- structure(list(`Salmon` = c("salmon River", "Ant Creek", "big Creek", "oso River", "linda Creek"), `baseline` = c(80874.384012, 361.1997, 5012.8311, 638.6912, 402.104433333333), `target` = c(160000, 720, 10000, 450, 800), `1992` = c(27618.4365, 0, 3587.61719, NA, NA), `1993` = c(100027.82328, NA, 5647.83116, NA, NA), `1994` = c(99414.57438, NA, 12896.93753, NA, NA), `1995` = c(235027.00518, NA, 32059.63037, NA, NA), `1996` = c(143004.6423, NA, 17191.2152, NA, NA), `1997` = c(112796.88894, NA, 27365.24435, NA, NA), `1998` = c(102858.8148, NA, 20539.17372, NA, NA), `1999` = c(94113.26562, NA, 21916.44213, NA, NA)), row.names = c(NA, -5L), class = c("tbl_df", "tbl", "data.frame")) fall.estimatestr(fall.estimate)#convert to class dataframefall.estimate <- as.data.frame(fall.estimate) #Remove all decimalsfall.estimate[,-1] <-round(fall.estimate[,-1],0)#Replace NA's' with dash '-'fall.estimate[is.na(fall.estimate)] <- "-" #Here all my columns get converted to character#Try to convert back to numericfall.estimate <- mutate_all(fall.estimate, function(x) as.numeric(as.character(x))) fall.estimate#But I get these warnings aand my dashes dissapearQuestion: How can I replace my NAs with dashes and keep all my dataframecolumns as numeric? Warning messages:1: In FUN(newX[, i], ...) : NAs introduced by coercion2: In FUN(newX[, i], ...) : NAs introduced by coercion3: In FUN(newX[, i], ...) : NAs introduced by coercion4: In FUN(newX[, i], ...) : NAs introduced by coercion5: In FUN(newX[, i], ...) : NAs introduced by coercion6: In FUN(newX[, i], ...) : NAs introduced by coercion7: In FUN(newX[, i], ...) : NAs introduced by coercion8: In FUN(newX[, i], ...) : NAs introduced by coercion9: In FUN(newX[, i], ...) : NAs introduced by coercion Thanks beforehand         [[alternative HTML version deleted]] ______________________________________________ [hidden email] mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-helpPLEASE do read the posting guide http://www.R-project.org/posting-guide.htmland provide commented, minimal, self-contained, reproducible code.

## Re: Preserving numeric columns

 Data frames are NOT spreadsheets. Don't treat them like spreadsheets. All elements in a column are parts of a vector which means they all have the same data type. On the other hand, if you want to generate formatted output in HTML, LaTeX, or Word, there are many tools for generating formatted tables in the data output phase of data analysis, and it is common to convert everything to character format intentionally then.

## Re: Preserving numeric columns

 You are correct. I didnt explain well and failed to mention that this is for knitr::kable.

## Re: Preserving numeric columns

 Then the polite next step is for you to indicate what that solution was so people searching the archives can learn from your question. Was it to set the kable option? options(knitr.kable.NA = '-')  On October 19, 2019 12:50:20 PM PDT, Felipe Carrillo <[hidden email]> wrote: >You are correct.
