...es, but iterating through the module's CallGraph is proving to be confusing. I believe I have to use CallGraphWrapperPass to get both module pass and its CallGraph. How do I iterate through the CallGraph in runOnModule()? A simple print callee names example would be highly appreciated.

Hello, trying to locate all the string commands in the base version of R, can't seem to find an area that describes them. I am in need to do some serious parsing of text data to create my dataset. Is there a summary link to all the character operators? string manipulations that would help in parsing text.

A general problem i run into, i know there must be a simple solution. I like to create a variable by appending a 1 for example, (i need to loop later on from 1 to X, thus the reason for this). So i assign the variable vplot with this value, however it has quotes and when i use it in a barplot, it throws an error. but the tcenter$X1 does exist, its an element of a data frame. So if i type

Hello, not understanding the output of prcomp, I reduce the number of components and the output continues to show cumulative 100% of the variance explained, which can't be the case dropping from 8 components to 3. How do i get the output in terms of the cumulative % of the total variance, so when i go from total solution of 8 (8 variables in the data set), to a reduced number of

Hello.. How do I get str() to show all variables in a data frame? It seems to be "list output truncated" at about 99 variables, the data frame has over 600 but i can't seem to figure out how to show all variables, we see list.len() but again can't seem to figure this out - help will be appreciated.

Hello, i see packages referencing using ODBC access to databases via R, are there any packages that use JDBC to submit SQL to a database and return into a data frame? -zubin

Hello, we are writing rich internet user interfaces and like to call R for some of the computational needs on the data, as well as some creation of image files. Our objects communicate via the SOAP interface. We have been researching the various packages to expose R as a SOAP service. No current CRAN SOAP packages however. Found 3 to date: RSOAP (http://sourceforge.net/projects/rsoap/)

Hello, we are receiving some data, sample below - with a weird time/date stamp format, we need some help with R on converting this time date stamp to a useable field in R, date and time in a data-frame. The developer says its the number of milliseconds since midnight, January 1, 1970. sample: *1232558018624* --------------------- How do I interpret the time stamp? Is there a date, i need

Hello, we are needing to generate optimal (Fractional) designs for discrete choice applications, where we will be using logistic regression or multinomial logit as the modeling technique. It looks like optFederov, in the AlgDesign package may work, but not sure if this algorithm works when the variable of interest is binary or nominal? Anyone who are experts in this area, anyone interested

Hello, I have some time series applications, where i have a large set of X variables (hundreds) and thousands of time data points (sampling every minute). I like to use the caret package to support the analysis, variable selection and model selection. However, reading the documentation, it looks like caret uses resampling methods. Not sure if these methods work with time series, as you
