Hi Lily,
I think below codes can work:
f<- list.files("D:/output/test/your folde
rname",full.names=TRUE,recursive=TRUE)
files<- grep(".csv", f)
files_merge<- data.frame()
for (i in 1:length(f[files])){
data<- read.csv(file=f[files][i],header=TRUE, sep=",")

Hello specialist,
I have a matrix in which there are NA,0,1 and 2 in each columns.
I wanna replace NAs with special proportion of 0,1 or 2 !

If in one column the number of NAs = 10 , # of 0=50 , #of 1=25 and # of
2=15
I want to replace 5 of 10

for example I have a matrix called data= 2000*5000 and I need to find the
high correlated variables between the variables in the columns! (Need 100
high correlated variables from 5000 variables in column)

Hi,
I have a huge .RData file and I need just to get the colnames of it. so is
there any way to reach the column names without loading or reading the

Hi there,
I want to find the intersection between two different data frame or

how can I find the intersection between
causing error and a code you hardly get
any sensible advice.

Hi there,
I have a matrix contain 0,1,2, NA elements.
I want to add a column to this matrix with name of idx . then for each
row, I should put 1 in this column (idx) if there is at least one 2 in that
row otherwise I should put 0 in this column!
for example mydata:
125 255 558
.
Hope this help !
