Dear group,
In pheatmap, is it possible to cluster select colmns.
For example, in a matrix of 10 rows and 20 columns. I want to cluster
only those columns 1-10 and cluster rows. Similarly, retaining the
same row clustering resulted from clustering of columns 1-10, I want
to enforce clustering of 11
Hello,
If I understand correctly, here are two different ways of doing what you
want.
1) base R.
i <- duplicated(df1[[2]])
j <- duplicated(df1[[2]], fromLast = TRUE)
res <- df1[i | j, ]
res[order(res[[2]]), ]# not strictly needed
2) with package dplyr. If you do not want to order by Mo
Do you mean like this?
tmp <- data.frame(v1 = c(1,2,1,4,2), v2 = c(10, 11, 10, 14, 11))
vals <- paste(tmp$v1, tmp$v2, sep ='')
tmp[which(vals %in% vals[duplicated(vals)]),]

This request is quite unclear. Can you make a reproducible example [1][2][3]
and provide data that represents the expected result corresponding to the input
data? The dput function is much much better than tabular form for this purpose.
For one thing, you mention ten columns, but they are not sh
Hi,
I have a dataset with ten columns, but I need extract only lines that has
common elements.
The columns are:
Animal Mother
[1,] 1143430
[2,] 1144134
[3,] 1146 3
[4,] 1147151
[5,] 1150230
[6,] 1156290
[7,] 1157227
[8,] 1159757
[9,]
I'm no expert in R internals or floating point computation, however, two things
come to mind.
First, I suspect the exact value is stored. It is just the printing that looks
rounded. That is likely because 0.001 completely dominates the rest. To print
in full precision, you would need over 200 d

Two quick answers:
1. using base R functions and data types the answer is 'no' - a double
(i.e. numeric) contains about 15 significant digits.
So 5.678e-100 is fine but 0.01 + 5.678e-100 will keep the
.0100 as the significant digits and "drop" the digits 80
7 matches
