[R] Parsing all rows & columns of a Dataframe into one column
Hi All,
I am using R for reading certain values in a dataset.
I have values in a data frame all scattered in different columns & rows,
some values might be NA as well.
e.g. below three columns V1, V2,V3, and their respective values.
V1
V2
V2
NA
NA
90
abc
89.09
$50
76799
NA
NA
02:15
def
1
What I would like to do is parse this data frame, create a new data frame, omit
all NA values. The new data frame would have one column, lets say Value column.
(order of the samples coming is not an issue)
New Data Frame (Output Required):
Value
abc
76799
02:15
89.09
def
90
$50
1
Any help would be appreciated.
Regards,
Anshuk Pal Chaudhuri

Hi Your HTML posting scrammbled your question a bit. If I understand correctly and as you want values of various type in one column, probably the easiest way would be. mat<-as.matrix(yourdata) mat<-na.omit(mat) dim(mat) <- NULL newdata <- data.frame(mat, stringsAsFactors=FALSE) Cheers Petr> -----Original Message----- > From: R-help [mailto:r-help-bounces at r-project.org] On Behalf Of Anshuk > Pal Chaudhuri > Sent: Monday, August 10, 2015 7:24 AM > To: r-help at r-project.org > Subject: [R] Parsing all rows & columns of a Dataframe into one column > > Hi All, > > > I am using R for reading certain values in a dataset. > > I have values in a data frame all scattered in different columns & > rows, some values might be NA as well. > > e.g. below three columns V1, V2,V3, and their respective values. > V1 > > V2 > > V2 > > NA > > NA > > 90 > > abc > > 89.09 > > $50 > > 76799 > > NA > > NA > > 02:15 > > def > > 1 > > > > > What I would like to do is parse this data frame, create a new data > frame, omit all NA values.

[R] Parsing all rows & columns of a Dataframe into one column
Thanks. Another way of handling is which I understood from other forum, thought to share here as well. data.frame(Value=dat[!is.na(dat)]) Regards, Anshuk Pal Chaudhuri -----Original Message----- From: PIKAL Petr [mailto:petr.pikal at precheza.cz] Sent: 10 August 2015 12:21 To: Anshuk Pal Chaudhuri <anshuk.p at motivitylabs.com>; r-help at r-project.org Subject: RE: Parsing all rows & columns of a Dataframe into one column Hi Your HTML posting scrammbled your question a bit.
