[Bioc-sig-seq] Vector of RangedData

[Zhu, Julie]

Hi,

I want to pass in a vector of RangedData to a function. But the vector
became one combined RangedData.

Here is an example with two RangedData.

peaks1= RangedData(IRanges(start = c(967654, 2010897, 2496704), end =
c(967754, 2010997, 2496804), names = c("Site1", "Site2", "Site3")), space =
c("1", "2", "3"), strand=as.integer(1))
 
peaks2 = RangedData(IRanges(start = c(967659, 2010898,  2496700, 3075866,
3123260), end = c(967869, 2011108, 2496920, 3076166, 3123470), names =
c("t1", "t2", "t3", "t4", "t5")), space = c("1", "2", "3", "1", "2"), strand
= c(1, 1, -1,-1,1))

Peaks=c(peaks1,peaks2)

Now Peaks become one RangedData. Is there a way to create a vector of
RangedData without combining all the RangedData into one? Thanks!

RangedData with 10 rows and 1 value column across 4 spaces
         space                 ranges |    strand
   <character>              <IRanges> | <integer>
p5           5 [167889600, 167893599] |         1
p1           6 [  1543200,   1555199] |         1
p2           6 [  1557200,   1560599] |         1
p3           6 [  1563000,   1565199] |         1
p4           6 [  1569800,   1573799] |         1
f5           5 [167888600, 167888999] |         1
f1           6 [  1549800,   1550599] |         1
f2           6 [  1554400,   1560799] |         1
f3           6 [  1565000,   1565399] |         1
f4           6 [  1569400,   1571199] |         1
