readContiguousValues.AbstractFileArray {R.huge} | R Documentation |
Reads sets of contiguous values in the file array. A set of contiguous values are values that are connecting without a break. It is much faster to read contiguous sequences at once than read each value separately.
## S3 method for class 'AbstractFileArray': readContiguousValues(this, indices, lengths=1, mode=getStorageMode(this), size=getBytesPerCell(this), offset=getDataOffset(this), ..., .checkArgs=TRUE)
indices |

length |

contiguous sets. |
mode |
The storage mode to read. |
size |
The number of bytes each values allocates on file. |
offset |
The file offset to the first value on file. |
... |
