R - Removing all empty columns and rows in data.frame when rows don't go away

If you want to remove all empty columns and rows from a data frame in R, you can use the dplyr package for a convenient approach. Here's an example:

library(dplyr) # Sample data frame data <- data.frame( A = c(1, NA, 3), B = c(NA, NA, NA), C = c(4, 5, 6) ) # Remove empty columns data <- data %>% select_if(~!all(is.na(.))) # Remove empty rows data <- data %>% filter_all(all_vars(!is.na(.))) # Print the result print(data)

In this example:

  1. select_if(~!all(is.na(.))) removes columns where all values are NA.
  2. filter_all(all_vars(!is.na(.))) removes rows where all values are NA.

Adjust the code according to your specific data frame and requirements. This approach ensures that both empty columns and empty rows are removed.

Examples

  1. "R remove empty columns and rows data.frame"

    • Code Implementation:
      # Sample data data <- data.frame( A = c(1, NA, 3), B = c(4, NA, NA), C = c(NA, NA, NA) ) # Remove empty columns and rows data <- data[, colSums(is.na(data)) < nrow(data), drop = FALSE] data <- data[rowSums(is.na(data)) < ncol(data), ]
    • Description: Removes empty columns and rows from a data.frame in R by filtering based on the presence of NA values.

  2. "R remove blank columns and rows from dataframe"

    • Code Implementation:
      # Sample data data <- data.frame( A = c(1, NA, 3), B = c(4, NA, NA), C = c(NA, NA, NA) ) # Remove blank columns and rows data <- data[, colSums(data == "") < nrow(data), drop = FALSE] data <- data[rowSums(data == "") < ncol(data), ]
    • Description: Eliminates blank columns and rows from a data.frame by filtering based on the presence of empty strings.

  3. "R remove all empty columns and rows in dataframe"

    • Code Implementation:
      # Sample data data <- data.frame( A = c(1, NA, 3), B = c(4, NA, NA), C = c(NA, NA, NA) ) # Remove all empty columns and rows data <- data[, colSums(is.na(data) | data == "") < nrow(data), drop = FALSE] data <- data[rowSums(is.na(data) | data == "") < ncol(data), ]
    • Description: Removes all empty columns and rows (including those with empty strings) from a data.frame in R.

  4. "R delete empty columns and rows dataframe"

    • Code Implementation:
      # Sample data data <- data.frame( A = c(1, NA, 3), B = c(4, NA, NA), C = c(NA, NA, NA) ) # Delete empty columns and rows data <- data[, colSums(is.na(data) | data == "") > 0, drop = FALSE] data <- data[rowSums(is.na(data) | data == "") > 0, ]
    • Description: Deletes empty columns and rows (including those with empty strings) from a data.frame in R.

  5. "R drop empty columns and rows from dataframe"

    • Code Implementation:
      # Sample data data <- data.frame( A = c(1, NA, 3), B = c(4, NA, NA), C = c(NA, NA, NA) ) # Drop empty columns and rows data <- data[, colSums(is.na(data) | data == "") > 0, drop = FALSE] data <- data[rowSums(is.na(data) | data == "") > 0, ]
    • Description: Drops empty columns and rows (including those with empty strings) from a data.frame in R.

  6. "R remove NA columns and rows from dataframe"

    • Code Implementation:
      # Sample data data <- data.frame( A = c(1, NA, 3), B = c(4, NA, NA), C = c(NA, NA, NA) ) # Remove NA columns and rows data <- data[, colSums(is.na(data)) < nrow(data), drop = FALSE] data <- data[rowSums(is.na(data)) < ncol(data), ]
    • Description: Removes columns and rows with NA values from a data.frame in R.

  7. "R eliminate empty columns and rows in dataframe"

    • Code Implementation:
      # Sample data data <- data.frame( A = c(1, NA, 3), B = c(4, NA, NA), C = c(NA, NA, NA) ) # Eliminate empty columns and rows data <- data[, colSums(is.na(data) | data == "") > 0, drop = FALSE] data <- data[rowSums(is.na(data) | data == "") > 0, ]
    • Description: Eliminates empty columns and rows (including those with empty strings) from a data.frame in R.

  8. "R drop NA columns and rows in dataframe"

    • Code Implementation:
      # Sample data data <- data.frame( A = c(1, NA, 3), B = c(4, NA, NA), C = c(NA, NA, NA) ) # Drop NA columns and rows data <- data[, colSums(is.na(data)) > 0, drop = FALSE] data <- data[rowSums(is.na(data)) > 0, ]
    • Description: Drops columns and rows with NA values from a data.frame in R.

  9. "R remove empty cells in dataframe"

    • Code Implementation:
      # Sample data data <- data.frame( A = c(1, NA, 3), B = c(4, NA, NA), C = c(NA, NA, NA) ) # Remove empty cells data <- na.omit(data)
    • Description: Removes empty cells (rows with any NA values) from a data.frame in R using the na.omit function.

  10. "R remove empty columns but keep rows in dataframe"

    • Code Implementation:
      # Sample data data <- data.frame( A = c(1, NA, 3), B = c(4, NA, NA), C = c(NA, NA, NA) ) # Remove empty columns but keep rows data <- data[, colSums(is.na(data) | data == "") > 0, drop = FALSE]
    • Description: Removes empty columns (including those with empty strings) from a data.frame in R while keeping all rows intact.
