[英]How to fix a table's column width on R Shiny using Formattable?
[英]R Shiny - filter two table and heatmap simultaneously (with cells of fix width)
我有两个输入表:label和main_plot。 我可以使用sidePanel中的控件来过滤图。 “ main_plot”中的列对应于“ label”的列。 我想同时使用控件过滤两个表。 (例如:如果在过滤后仅看到“标签”的第一列和第二列,我只想看到图中的第一列和第二列)另外,我希望表格和图中的单元格宽度相同。 实际上,我可以将过滤条件从output $ label复制到output $ main_plot,但是单元格的问题仍然存在...感谢您的任何建议Kamila
编码:
shinyUI(fluidPage(
titlePanel("title panel"),
sidebarLayout(
sidebarPanel(
selectInput("select_name",
label = "name",
choices = c("all", "A", "B", "C", "D","E"),
selected = "all"),
selectInput("select_type",
label = "Type",
choices = c("all", "M", "FFF"),
selected = "all")
),
mainPanel(
tableOutput("lab"),
plotOutput("main_plot")
)
)
))
f <- function () sample(seq(1:10), 25, replace=TRUE)
in1 <- cbind (f(), f(), f(), f(), f(), f())
label <- data.frame(L1= c(rep("A", 5), rep("B", 5), rep("C", 5), rep("D", 5), rep("E", 5)), L2=(sample(c("M", "FFF"), 25, replace=TRUE)))
shinyServer(function(input, output) {
output$main_plot <- renderPlot({
plot.new()
par(mar=c(0, 0, 0, 0)); barplot(1:10, xaxs="i", ylim=c(0,10), space=0)
image(in1)
})
output$lab <- renderTable({
label_sub <- label
if (input$select_type!="all")
{
label_sub <- subset(label_sub, label_sub$L2==input$select_type)
}
if (input$select_name!="all")
{
label_sub <- subset(label_sub, label_sub$L1==input$select_name)
}
t(label_sub)}, include.rownames=FALSE)
})
最终,我和Joe Cheng(非常感谢)对以下解决方案进行了实施。 https://groups.google.com/forum/#!topic/shiny-discuss/hW4uw51r1Ak
f <- function () sample(seq(1:10), 25, replace=TRUE)
in1 <- cbind (f(), f(), f(), f(), f(), f())
label <- data.frame(L1= c(rep("A", 5), rep("B", 5), rep("C", 5), rep("D", 5), rep("E", 5)), L2=(sample(c("M", "FFF"), 25, replace=TRUE)), ID=seq(1,25))
label_sub <- label
shinyServer(function(input, output) {
#Create a reactive object which will hold the table in actual state.
labelSub <- reactive({
label_sub <- label
if (input$select_type!="all")
{
label_sub <- subset(label_sub, label_sub$L2==input$select_type)
}
if (input$select_name!="all")
{
label_sub <- subset(label_sub, label_sub$L1==input$select_name)
}
return(label_sub)
})
output$main_plot <- renderPlot({
plot.new()
#Access column IDs from the reactive
IDs <- labelSub()[,3]
par(mar=c(0, 0, 0, 0)); barplot(1:10, xaxs="i", ylim=c(0,10), space=0)
#get corresponding columns of the source table of the heatmap for_plot <- in1[IDs,]
#If just one column is selected the output is not a matrix but a vector. Therefore we need to convert it to matrix and transpose it.
if(is.matrix(for_plot)==FALSE)
{for_plot <- t(as.matrix(for_plot))}
image(for_plot)
}, width = function () {60*nrow(labelSub())})
output$lab <- renderTable({
t(labelSub())}, include.rownames=FALSE)
})

I have two input tables: label and main_plot. I am able to filter the plot using controls in the sidePanel. Column in "main_plot" corresponds to columns of "label". I want to filter both tables using controls simultaneously. (e.g.: if I see only first and second column of "label" after filtering I want to see only first and second column in the plot) Additionally I would like to have the same width of cells in the table and in the plot. Actually I could copy filtering criteria from output$label to output$main_plot but the problem with the widht of cells remains... Thank you for any suggestions Kamila
The code:
shinyUI(fluidPage(
titlePanel("title panel"),
sidebarLayout(
sidebarPanel(
selectInput("select_name",
label = "name",
choices = c("all", "A", "B", "C", "D","E"),
selected = "all"),
selectInput("select_type",
label = "Type",
choices = c("all", "M", "FFF"),
selected = "all")
),
mainPanel(
tableOutput("lab"),
plotOutput("main_plot")
)
)
))
f <- function () sample(seq(1:10), 25, replace=TRUE)
in1 <- cbind (f(), f(), f(), f(), f(), f())
label <- data.frame(L1= c(rep("A", 5), rep("B", 5), rep("C", 5), rep("D", 5), rep("E", 5)), L2=(sample(c("M", "FFF"), 25, replace=TRUE)))
shinyServer(function(input, output) {
output$main_plot <- renderPlot({
plot.new()
par(mar=c(0, 0, 0, 0)); barplot(1:10, xaxs="i", ylim=c(0,10), space=0)
image(in1)
})
output$lab <- renderTable({
label_sub <- label
if (input$select_type!="all")
{
label_sub <- subset(label_sub, label_sub$L2==input$select_ type)
}
if (input$select_name!="all")
{
label_sub <- subset(label_sub, label_sub$L1==input$select_ name)
}
t(label_sub)}, include.rownames=FALSE)
})
