Removing space between numeric values in R

r remove whitespace from data frame
r trim whitespace dplyr
r remove spaces from column names
trimws r
r remove extra whitespace
replace space with blank in r
space character in r
r remove tab

My list consist values as shown.

Mylist:
[[1]]
[1] 1 1 1 0 1 1

[[2]]
[1] 0 0 0 0 1 0

[[3]]
[1] 0 0 0 0 1 0

I need to convert this binary values to decimal. I am using BinToDec() function. But here values are space separated. How to get the values like 111011, 000010 etc in that list. I have tried with gsub, but it removes spaces in string. Thanks!


Try using gsub with lapply to remove all whitespace:

BinToDec <- function(x) 
    sum(2^(which(rev(unlist(strsplit(as.character(x), "")) == 1))-1))

lst <- list("1 1 1 0 1 1", "0 0 0 0 1 0", "0 0 0 0 1 0")
unlist(lapply(lst, function(x) BinToDec(gsub("\\s+", "", x))))

[1] 59  2  2

I took the above BinToDec function from this SO answer, which maybe is also where you saw it.

Edit:

If you actually have a list of integer vectors, then use this option:

lst <- list(c(1,1,1,0,1,1), c(0,0,0,0,1,0), c(0,0,0,0,1,0))
unlist(lapply(lst, function(x) BinToDec(paste(as.character(x), collapse=""))))

Thanks.as.numeric(paste(as.character(Mylist[[i]]),collapse = "")) solves the issue.

[Solved] How Do I Remove The Space Between Numbers , It's difficult to remove the space between numbers with String.Replace or String.​Trim, because they are remarkably dumb methods: they just  Missing values in data science arise when an observation is missing in a column of a data frame or contains a character value instead of numeric value. Missing values must be dropped or replaced in order to draw correct conclusion from the data. In this tutorial, we will learn how to deal with missing values with the dplyr library. dplyr


Package (StringR)

The code below allows to find certain character and remove or replace

Code str_replace_all(x, " ", "")

Explanation

str_replace_all(Dataset, "character you are looking up ", "replacement character ")

If only for a certain row be sure to do the following

str_replace_all(Dataset$Row, "character you are looking up ", "replacement character ")
