I am not sure what the spldf pkg is, I hope it is a typo for sqldf 

# to install all packages and its dependencies simple use the below code.  
install.packages("Package_Name", dependencies= True).

Looks Like you are working with R-Hadoop. Sometimes the packages are not available on CRAN, you can download them and install them on your local computer and pass the path. 

install.packages("path_to_installed_package.tar.gz", repos=NULL, type="source")

The following link may be helpful. Run an R job on Hadoop http://www.rdatamining.com/big-data/r-hadoop-setup-guide

    # For checking the packages installed, use          
    > installed.packages() 
    > In_P <- installed.packages()[,1]

    # For checking all the available packages, use
    > available.packages()
    > Av_P <- available.packages()[,1]

    # Removing Installed packages from available packages list
    > Un_P <- Av_P[!Av_P %in% In_P]  

    # For installing Packages which are not installed already
    > install.packages(Un_P)
