Thank you.
To correct myself, I can indeed reproduce this with R --vanilla too.
A reproducible example is:

snpStats imputed SNP probabilities
Hi,
Does anybody know how to obtain the imputed SNP genotype probabilities from the snpStats package?
I am interested in using an imputation method implemented in R to be further used in a simulation study context.
I have found the snpStats package that seems to contain suitable functions to do so.
As far as I could find out from the package vignette examples and its help, it gives the

Packages for snp, CNV data
Hi,
In addition to GADA, what are the available package in R and bioconductor to analyze amplification, deletion, LOH and indels of CNV, SNP data? Any reference is welcome.

Plotting question: how to plot SNP location data?
Hello,
I would like to plot specific SNPs with their exact locations on a
chromosome. Based on my genotyping results I would like to separate
these SNPs in three different categories: 1, 2 and 3 and use different
colours to represent these categories. The script below generates the
sample data. I can plot these with the image function using the
following:
val <- 1:3
samp <- sample(val,

Generating missingness on SNP data
Dear all,
I generated a dataset with 500 unrelated individuals and 10 biallelic
SNPs. From this dataset,I would like to create data with 5% missingness on
genotype information at random and also data with 5% genotyping error.
Can someone help me with how I can do it.

SEV, SEV-ES, SEV-SNP
When SEV is enabled in domcapabilities does that just mean any of SEV,
SEV-ES, SEV-SNP is possible on the hardware?
Similarly, does enabling SEV as a launchSecurity option in a domainXML mean
that whichever SEV is available will be enabled? And if the guest policy
has the ES flag set, it will not be created unless ES is enabled?
Sorry if these questions don't make sense or are ill-formed.

SNP Tables
Hello,
I have indicators for the present of absent of a snps in columns and the
categorey (case control column). I would like to extract ONLY the tables and
the indices (SNPS) that give me 2 x 3 tables. Some gives 2x 2 tables when
one of the allelle is missing. The data look like the matrix snpmat below:
so the first snp should give me the following table: (aa=0, Aa=1 and AA=2)

Character SNP data to binary MAF data
Hi
I am sure there is a function out there already but I couldn't find it.
I have SNP data, that is, a matrix which contains in each row two
characters (they are different in each row) and I would like to
convert this matrix to a binary one according to the minor allele
frequency. For non-geneticists: I want to have a binary matrix
for which in each row the 0 stands for the less frequent

R coding to extract allele frequencies from NCBI for ALL alleles of one SNP?
Dear All,
The following code extracts from NCBI very nice output for ONE allele of a SNP (often the allele with the second largest frequency - usually termed the minor allele). It gives an average minor allele frequency from all NCBI sources (which is what I want, except I'd like the addition of data for all the other alleles of one SNP) plus a table of minor allele frequencies from each

download.file does not process gz files correctly (truncates them?)
Dear all,
I've noticed by trying to download gz files from here :
https://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM907811
At the bottom one can download GSM907811.CEL.gz . If I download this
manually and try
oligo::read.celfiles("GSM907811.CEL.gz")
everything works fine. (oligo is a bioConductor package)

**Maybe this bug needs to be understood further before applying the
patch because patch is most likely also wrong**
Because, from just looking at the expressions, I think neither the R

omittedSig <- omittedSig && (signature[omittedSig] != "missing")
nor the patched version (I proposed):

Can someone recommend a package for SNP cluster analysis of Fluidigm microarrays?
I know that there are quite a few packages out that there for cluster
analysis. The problem that I am facing is finding a package that will not
incorporate all my samples into clusters but just the samples that fit a
threshold (that I have not set yet and may need help finding the right
level) for genotyping. It should be able to "no call" samples outside the
clusters. It also needs to

FW: Index out SNP position
I think you mean between column 1 and 2 of A? Why is 36003918 not
included? It is clearly between 35838396 and 36151202 in the first row of A.
My earlier solution should work fine. Just create a new matrix AX that has
the columns switched so that the start is always column 1 and use that to
identify the ones you want to select. That way you are not modifying B. This
will be faster than checking

If a minimal reprex is hard to construct, could you perhaps instrument your version of R to include a browser() call at the start of the
