Package Version: NanoStringNorm 1.2.0
R Version: 3.3.2
OS: Windows 10 x64
When loading a series of 144 raw Nanostring RCC files using
NanoStringNorm::read.markup.RCC(), processing of the 32nd file fails with the error:...when creating the
sample.contextConnection (https://github.com/cran/NanoStringNorm/blob/1.2.0/R/read.markup.RCC.R#L55)help("connections", package="base")states that the maximum number of allocated connections is 128 (with 3 reserved forstdin, stdout, stderr) and I can see thatread.markup.RCC()is opening textConnections but not closing them and hitting the hard limit of 125 usable connections.As each call to
read.markup.RCC()opens 4 connections, all 125 available will be allocated by the time sample.con is created on the 32nd iteration.Simply closing the connection once the data has been read from the file resolves this problem.
