I hope that someone can help me with this. I've try the aggregate(.~ Guar1+Bucket2, df, mean, na.rm = FALSE)īut it then excluding all NA in the final table.Īnd if I set all the NA value in df equal to 0 then I would not have the desire average. The data table looks for instance like this Guar1 Bucket2 1 2 3 4 Total MonthĢ0 0.4 2.29 5.38 14.91 14.18 36.76 201111Īnd the final table Guar1 Bucket2 1 2 3 4 Total I'm struggling with finding something to aggregate my data frame by taking the mean and ignoring the NA value, but the end results would still show a missing value them. # Calculate t-statistic for confidence interval: # Confidence interval multiplier for standard error Names ( datac ) <- measurevar names ( datac ) <- "sd" names ( datac ) <- "N" datac $ se <- datac $ sd / sqrt ( datac $ N ) # Calculate standard error of the mean drop = TRUE ) # Collapse the dataįormula <- as.formula ( paste ( measurevar, paste ( groupvars, collapse = " + " ), sep = " ~ " )) datac <- summaryBy ( formula, data = data, FUN = c ( length2, mean, sd ), na.rm = na.rm ) # Rename columns You can install it from CRAN with: install.packages ('dplyr') You can see a full list of changes in the release notes. SummarySE <- function ( data = NULL, measurevar, groupvars = NULL, na.rm = FALSE, conf.interval =. dplyr Romain Francois We’re happy to announce the release of dplyr 1.0.4, featuring: two new functions ifall () and ifany (), and improved performance improvements of across (). # conf.interval: the percent range of the confidence interval (default is 95%) # na.rm: a boolean that indicates whether to ignore NA's # groupvars: a vector containing names of columns that contain grouping variables # measurevar: the name of a column that contains the variable to be summariezed Syntax of median median ( x, na.rm FALSE, ) Parameters: x It is an input vector of type Numeric na.rm Defaults to FALSE. # Gives count, mean, standard deviation, standard error of the mean, and confidence interval (default 95%). Syntax of median () The following is the syntax of the median () function that calculates the median value. To use, put this function in your code and call it as demonstrated below. For example, if you want it to ignore any NAs in the HeadWt column, use sum(is.na(Headwt)). Remove NA when Summarizing data.table in R (2 Examples) r - Ignoring NA when.
