R ggplot2包加载

Question

我很新的与R(版本3.0.3)和我正在一个小应用程序与shiny和ggplot.一切都很好,然后我似乎无法正确加载包.

这是我的代码和错误消息:

library(shiny)
library(ggplot2)
# Error in get(Info[i, 1], envir = env) : lazy-load database 'P' is corrupt
# In addition: Warning message:
# In get(Info[i, 1], envir = env) : internal error -3 in R_decompress1
# Error: package or namespace load failed for ‘ggplot2’**

library(reshape2)
# Error in get(Info[i, 1], envir = env) : lazy-load database 'P' is corrupt
# In addition: Warning message:
# In get(Info[i, 1], envir = env) : internal error -3 in R_decompress1
# Error: package or namespace load failed for ‘reshape2’** 

shinyUI(pageWithSidebar(
       headerPanel( h3(textOutput("athleteTxt"))),
       sidebarPanel(selectInput("athlete", "Changer d'athlete :", paste(dataNom$Nom, dataNom$Prenom))),
       mainPanel(tabsetPanel(
       tabPanel('Progression individuelle',
               plotOutput("graphInd")),
      tabPanel('Comparaison par poste',
               plotOutput("graphPosition"),
               tableOutput("tabPosition")),
      tabPanel('Comparaison avec pro',
               selectInput("positionStd", "Choisir un standard pour comparer :",
                           dataStandardsP$Position),
               tableOutput("tabStandards")),
    ))
 ))

谢谢你的帮助.
