从数据框中的两列中删除 NA 上移

Question

I have this data frame

                               atac.v1.pbmc.5k.possorted.bam.bam possorted.bam.bam
chr1.9941.10736                                 NA                NA
                                             13196              4348
chr1.10918.11476                                NA                NA
                                              2624               658
chr1.20874.21591                                NA                NA
                                               652               343

and I would like to remove the NAs and get this:

                               atac.v1.pbmc.5k.possorted.bam.bam possorted.bam.bam
chr1.9941.10736                              13196              4348                 
chr1.10918.11476                             2624               658                  
chr1.20874.21591                             652                343 
                                             

There are many questions about removing NAs, but I couldn't manage to use any of them to do this. I tried remove NAs and various code to remove white spaces, but wasn't able to.

Answer 1

For R a similar question was already asked here .

Thus when you want to solve it in R you can eg. use the following:

df = data.frame('name'=c('a',NA,'b',NA), 'val'=c(NaN, 1, NaN, 5))
library(dplyr)
na.omit(transform(df, name = lag(name)))

The df is only given to have a minimal running program.

Hi @RicS and @Robert Wilson, after I put dput(df) i get this

"", "s37d5.35353959.35354523", "", "s37d5.35354792.35354991", 
"", "s37d5.35364108.35364390", "", "s37d5.35365154.35365375", 
"", "s37d5.35371939.35372823", "", "s37d5.35373959.35374177", 
"", "s37d5.35382938.35383151", "", "s37d5.35391117.35391934",

"", "s37d5.35453892.35454283", ""), c("atac.v1.pbmc.5k.possorted.bam.bam", 
"possorted.bam.bam")))

I just copied and pasted some of it.
