Removing only blank cells in R (not the entire row or column)

Question

So I want to remove all cells that are blank within my dataset. So for example, if I had something like this, where the (..) represents blank numbers:-

1 10 .. 4         


        

Answer 1

If your data.frame is named df then:

df[df == ".."] <- NA

In order to get NAs, then:

func<-function(i){
  x<-as.numeric(as.character(df[,i][!is.na(df[,i])]))
  xna<-as.numeric(as.character(df[,i][is.na(df[,i])]))
  newx<-c(x,xna)
}

do.call(cbind,lapply(1:length(df[1,]),func))

> do.call(cbind,lapply(1:length(df[1,]),func))
     [,1] [,2] [,3] [,4]
[1,]    1   10   10    4
[2,]   14    9   12    8
[3,]   NA    8   NA   16
